Study on Deformation Modulus of the Desert Sand

摘要: 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符合沙漠砂的变形性质Abstract: 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 qc-E0 and i>N-E0.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 qc-E0 and i>N-E0 are in accord with the deformation property.
