格尔木地区砾石砂的动力学特性及路堤施工措施研究

Dynamics Properties of Ge'ermu Gravel Sand and Methods of Civil Embankment Construction

通过对格尔木地区砾石砂的动三轴试验 ,得到了影响循环荷载作用下砾石砂变形特性的主要因素为循环应力比和围压 。

A serial of dynamic triaxial tests was conducted for compacted gravel sand. Based on the test results, it concluded that the cyclic stress ratio and confining pressure are the mainly factors which affected the deformation property of the studied Ger'ermu sand under cyclic loading, and the suggestion about the embankment construction is advanced.
