For getting more accurate characteristic value of subgrade bearing capacity,Combined with the engineering instance,it describes process of the shallow plate load test at three points in the soil of the project of Fengyuan community in Handan,and the test results from the test first-hand data are obtained,then the load and settlement amount( p-s),lgp-lgs and other curve graphs are made,according to different methods,such as the method of intensity and relative settlement control,to get characteristic value of subgrade bearing capacity at three points under meeting the specific conditions,after brief analysis of them,the characteristic value of subgrade bearing capacity is determined. Finally,the value will be verified with the results of cone penetration test.
