摘　　要：针对强夯回填土的物理力学性质,建立强夯回填土地基的非线性沉降计算模型。提出不同条件下土的变形模量关系。根据平板荷载试验的P-S曲线引入任意点切线模量思想求得某一层土层的变形力学参数,然后利用提出的变形模量关系式求取各计算土层的变形力学参数。通过对工程实例的计算与分析,并将计算结果与实测数据比较,证明方法合理性和可行性。The model of nonlinear settlement calculation is established by the physical and mechanical properties of the bankette. The deformation modulus of soil under different conditions is put forward. According to the P-S curve of the plate load test, the deformation parameters of a layer of soil layer are obtained by using the tangent modulus theory. Through the calculation and analysis of engineering examples, the results are compared with the measured data, and the rationality and feasibility of the meth- od is proved.
