沙漠砂变形模量研究

Study on Deformation Modulus of the Desert Sand

在对塔克拉玛干沙漠砂大量现场原位试验、室内大型原位模拟试验的基础上 ,提出了用静力触探方法 (CPT)和标贯法 (SPT)获取沙漠砂变形模量的经验公式 qc E0 和N E0 ,并把经验公式表格化。依据这些经验公式反算现场与室内载荷试验的沉降量 ,结果表明 ,线性经验公式 qc E0 、N E0

On the basis of study on the desert sand through a lot of field in-situ tests and laboratory simulation in-situ tests,CPT and SPT are used to get the empirical formulae about deformation modulus q c?E 0 and N?E 0.?Furthermore, the two formulae are tabulated. According to above empirical formula,field and laboratory settlement is back calculated. The result shows the linear formulae of q c?E 0 and N?E 0 are in accord with the deformation property.
