Abstract
Sidomukti II bridge is one of the main accesses of the village of Banuroja to the downtown of Pohuwato Regency. This bridge was built in 2017 with bored pile foundation construction. In analyzing the carrying capacity of the soil, surely it is not free from direct research in-situ test and laboratory tests. The large carrying capacity of the soil is obtained from the analysis of soil investigation. Soil investigations conducted in the field in the form of a Standard Penetration Test (SPT), and drilling. SPT test is widely used in Indonesia because it is very useful to obtain variations in soil density. While drilling is used to describe the soil profile at a certain depth.
The research method is in the form of analysis of bearing capacity based on comparison of the results of in-situ tests and laboratory tests. Soil results from drilling are taken in 2 conditions namely disturbed conditions to describe each layer and undisturbed samples to be tested in a laboratory with a direct shear test or unconfined compressive strength.
The results show the value of the carrying capacity of the land permit based on the results of the in-situ test gives a greater value than the value of the carrying capacity of the land permit based on laboratory test results.
