Chapter 5. Soil and Geotechnical Investigations
24. Soil Report Review Process: Soil/Geotechnical report prepared by the licensed engineer should be reviewed by the Expert such as Professional Engineer in Soils or having PhD qualification in Geotechnical Engineering or Proof Engineer having Consulting Licence in Geotechnical Engineering.
25. Seismic Hazard Assessment: For assessing the seismic hazard, the geotechnical report should be prepared by Professional Engineer in Soils or having PhD qualification in Geotechnical Engineering.
(1) Bed Rock Response: Probabilistic Hazard Analysis: Using the BCP-2007 seismic zonation, the bed rock Peak Ground Acceleration (PGA) can be calculated for the site of interest. (2) Seismic site classification: For site classification shear wave velocity profile is required. Therefore, SASW (Spectral Analysis of Surface Waves) or MASW (Multi-channel Analysis of Surface Waves) geophysical tests are required.
(3) Surface Response: Using the BCP-2007 site amplification factors can be computed and multiplied to compute the surface response. As residential buildings in Pakistan either are single or double story therefore PGA will be reliable intensity measure to account for the level of expected ground motion intensity at site of interest.For the important building with multiple stories design response spectra can be defined as per the BCP-2007 guidelines. For site class F site specific response analysis must be carried out.
(4) Ground motion selection: In case, the time history analysis is required for the building seismic design, suite of ground motions should be selected as,
(a) Locate the site of interest on the fault map given in BCP -2007, compute deterministic scenario.
(b) Using the computed deterministic scenario select the three (03) set of recorded acceleration time histories.
(c) In case buildings are single or double story with fundamental period less than 1s, use the PGA scaled motion, for mid to high rise building use response spectrum compatible time histories. The only required geophysical test for this step is MASW or SASW to compute the average shear wave velocity profile. These information will be provided to structure engineer for evaluation of
42
“Seismic Design”.
(5) Liquefaction Potential: Mostly saturated soil (particularly sandy soil) if subjected to dynamic loading are susceptible to liquefaction. In case of earthquake prone area, the liquefaction is expected if the Rupture distance (source to site distance) is less than 100 km. If the above conditions are existing, the soil must be checked for liquefaction potential. The liquefaction potential of the sub-surface can be evaluated by performing standard penetration test (SPT), or cone penetration test (CPT), or shear wave velocity (Vs) test and incorporating the correlation between cyclic resistance ratio (CRS) and SPT/CPT/Vs.The liquefaction can also be assessed by performing one dimensional effective stress site response analysis.
(6) Potential Landslide and Slope Instability: In case the site is location on slope or face slope, it is required to evaluate the seismic slope stability such that the setback distance is not interspacing the failure plane of slope. Following methods maybe used to evaluate seismic slope stability,(a) Pseudo-static method, and (b) Sliding block method. The seismic load/demand in terms of PGA should be calculated as defined in Seismic Hazard section. To define the shear strength and stiffness of soil in seismic slope stability tests should be performed to determine required soil properties (c, phi, unit weight, and stratigraphy).
26. Soils and Foundations.- (1) Introduction: It is important that before a field investigation program is developed a preliminary site characterization based on published literature and clients and consultant’s information, information from old constructions etc. be prepared. Geotechnical properties of soils highly influence the stability of civil engineering structures. The occurrence and distribution of soils in nature varies from location to location. Therefore, site specific geotechnical investigation is always needed.
(2) Soil Profile: In view of the structural design as per Sec 4.3 and 4.4 of BCP-2007, type of Sub-Soil for foundation should be thoroughly ascertained by geo-technical investigation under the direct supervision of qualified and experienced geo-technical engineers. Initially, few bore holes (number and depth of bore holes will be suggested by the geotechnical expert) are made or a test pit is opened to establish in a general manner the stratification, types of soil to be expected, and possibly the location of the groundwater table. If the initial borings indicate that the upper soil is loose or highly compressible, one or more borings should be taken to rock or competent strata. Following test should be performed on the soil samples collected at different depth during boring.
43
(a) Soil gradation (sieve analysis and or hydrometer test)
(b) Liquid limit test
(c) Plastic limit test
(3) Standard penetration tests (SPT) or Cone Penetration Test (CPT) must be performed at the site to get knowledge about the subsurface stratigraphy encountered in each bore hole up to the desired depth. For seismic active zones Shear wave velocity tests (SASW or MASW geophysical tests) must be performed to characterize the site class. The information gathered from the above tests will be presented in the form of Bore loges. Geotechnical investigation report must contain the bore loges.
(4) Bearing capacity: The foundation to the structures is provided to safely transmit the load of the superstructure to the safe bearing capacity of the soil. The foundation can be a, (1) shallow foundation or (2) deep foundation, depend on the available bearing capacity and size of the structure. In view of the foundation construction as per Sec 4.5 of BCP-2007, the safe bearing capacity of the foundation soil must be calculated for any type of foundation.
(5) Shallow foundation: The bearing capacity for shallow foundation should be calculated by any of the following methods.
(a) Analytical methods: The analytical method proposed by Terzaghi (194) can be used to calculate the bearing capacity of shallow foundations. Shear strength parameters i.e. cohesion and the internal friction angle is used to calculate the bearing capacity of soil. The shear strength parameter can be determined by conducting the following tests;
(b) Direct shear test
(c) Triaxial test
(d) Unconfined test
(e) The relative density test
(f) Plate load test
(6) The type of test will be selected by a qualified and experienced geo-technical engineer. The bearing capacity of shallow foundation can also be determined by performing the plate load test in the field on the desired depth. The foundation must also be checked for settlement and shear failure. One dimensional consolidation test must be performed to assess settlement of the foundation. It is highly recommended for multi-story buildings and important buildings that the
44
foundation must be checked for settlement and shear failure by using advanced soil constitutive models in computer simulation programs.
(7) Deep foundation: Deep foundation is provided if the desired bearing capacity is not found at shallow depth. Any of the following tests must be performed to find the desired bearing capacity depth.
i. Standard Penetration Test (SPT)
ii. Cone Penetration Test (CPT)
A qualified geo-technical engineer will have to verify the tests results and suggest the type of the foundation.
Proper investigation of lateral stresses and strains before excavation must be carried out.
(8) Design Parameters of Foundations in Seismic Zones: The seismic factor (kh) must be considered in calculated the bearing capacity factors for foundations in seismic zones 3 and 4.Raft foundation or piles foundation is recommended if the overturning moment due to seismic loading is high. It is highly recommended for multi-story buildings and important buildings that the stability of the foundation against earthquake loading must be checked by using advanced soil constitutive models in computer simulation programs.
