Abstract: It's vital to acquire bearing capacity of soft rock foundation for large architecture such as high-rise buildings and nuclear power plants located on soft rock. Because engineering attribute of soft rock is special, it's not suitable to use saturated axial compressive strength to define bearing capacity of soft rock. And loading test is time-consuming and expensive. By means of pressuremeter test on Paleogene sandy soft rock foundation of Jiyang nuclear power plant in Anhui province and analysis of test data, this paper testifies the adaptability of pressuremeter test in obtaining bearing capacity of soft rock and acquires the formula of soft rock bearing capacity versus depth, i.e.fa=97.806H+882.39.
