Comprehension of Conventional Methods for Ultimate Bearing Capacity of Shallow Foundation by PLT and SPT in Southern Bhutan

Shallow foundations are very distinctive in Bhutan since construction of buildings regulated to 7-8 story and the superstructure loads not high compared high-rise elsewhere. However, safety depends primarily on stability subsoil. This can be evaluated by estimating Ultimate Bearing Capacity (UBC) it is measure subsoil strength. In current study, field test such as Plate Load Test (PLT) Standard Penetration (SPT) conducted study area which most common conventional methods adopted given typology infrastructures. Detail analysis performed for PLT SPT data collected from southern parts assess shear characteristics The exploration was carried out at embedment depth 1.5 m both tests. directly provides UBC through load settlement plot. With N-values, estimated square footing using empirical correlations proposed Terzaghi 1943 Meyerhof 1963. results comprehend design parameters. Both in-situ resulted close estimation UBC. SPT, indicate Meyerhof's correlation more conservative suggesting safe economical foundation design. parametric deduce validate among parameters used. lithology reviewed belt resistivity profiles underlying strata region have been reported similar investigation this study.
