| 摘 要： | 研究了沉积作用对成层地基自重应力与沉降的影响，给出了相应的计算公式，并对几种情况下的计算结果进行了分析比较。结果表明，考虑沉积作用后自重应力将沿深度呈非线性变化，沉积作用对地基沉降的影响随荷载和土压缩性以及土层厚度的增加而增大。该研究结果可用于成层地基一维大应变固结分析。

| Abstract: | The influence of sedimentation on overburden pressure and settlement of layered soil is studied and the relevant formulas are developed. The results from several numerical examples are analyzed and compared. It is shown that the overburden pressure is varied with depth in a non-linear way when sedimentation is considered, and the influence of sedimentation on settlement of layered soil is increased with load,soil compressibility and thickness of soil layer. The presented work is useful,especially for large strain consolidation analysis of layered soil. |
