BEARING CAPACITY OF LATERITIC SOILS IN CHANTHABURI
Keywords:
Foundation design, lateritic soils, Chanthaburi, bearing capacityAbstract
The objective of this research was to study the bearing capacity of lateritic soils in Chanthaburi for foundation design. The research methodologies were including comparing the plate bearing capacity with the theoretical Terzaghi’s bearing capacity equation taking soil friction angle and cohesions from the correlation graph using standard penetration test values (SPT-N values) and from the laboratory test; the direct shear test; finding the correlation graph with the SPT-N value to determine the empirical equation. The plate bearing tests were conducted at the eleven sites around Chanthaburi. The plate bearing capacity values were then compared to various theoretical approaches. The results showed that the bearing capacity from the plate bearing test yielded the maximum values following by the bearing capacities calculated from Terzaghi’s equation with the soil parameters (c and ) obtained from direct shear tests and the one calculated from SPT test, respectively. Finally, correlation equation between average ultimate bearing capacity (qu) and SPT-N value can be expressed as qu = 8.88N t/m2 for N<20.
