| Abstract: | Sand-gravel cushion has some engineering characteristics of good compactibility,great filling density,high shear strength,less settlement and high bearing capacity etc. The program of sand-gravel cushion is used to the main building ground treatment of Zouxian 1000MW unit power plant,and a reasonable construction technology and design parameters are confirmed through testing. Based on the subsidence observation data of the buildings,the settlement and deformation characteristics of the building with sand-gravel foundation is analyzed in detail,and the settlement and mechanical characteristics of cushion foundation is analyzed by the method of three-dimensional numerical simulation. |
