Study on Xianning Nuclear Power Station Field-leveling Engineering In-situ Direct Shear Test of Hubei Province

Combined with Hubei xianning nuclear power station field-leveling engineering,this paper discusses the key steps in thrust and shear test from the aspects of test site selection,test material preparation,test arrangement,equipment installation,load application,etc.According to the test record and field data,it obtained the shear strength parameters and drew the relation curve of soil destruction of shear stress and displacement.
