摘要：Expansive soil is a kind of soil that has ability to shrinkage and swelling. According to Ronny (2014) Jatinangor area has expansive soil that is so very influential in the planning of infrastructure construction. This research aimed to measure the bearing capacity of the very expansive soils in Jatinangor area and to determine the correlation between activity number of soil and its bearing capacity. The method used is to collect the soil physics and mechanics data. Based on the soil mechanics data, the research location is divided into three zones of allowable bearing capacity, those are zone with allowable bearing capacity < 4 T/m2, zone with allowable bearing capacity 4-7 T/m2, and zone with allowable bearing capacity > 7 T/m2. The correlation between activity number and bearing capacity of soil follows the equation qa = -1.9505(A) + 6.957 with correlation coefficient is -0.7911.
