摘要

研究了地下水浸没对附加应力减小的作用，同时分析了附加应力变化对最终沉降量的影响，给出了考虑地下水浸没作用的大、小应变条件下的固结沉降计算公式，并对几种工况下的计算结果进行了对比分析。结果表明，考虑地下水浸没作用对地基固结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，采用大变形固结理论计算固结沉降较符合实际情况。

Abstract

The reducing of additional stress due to groundwater submergence is studied; and the influence of the variation of additional stress on final settlement is analyzed. The consolidation settlement formulas taking into consideration submergence of small-strain and large-strain are derived. The results from several numerical examples are analyzed and compared. It is shown that the influence of submerge on consolidation settlement of ground increases with load

soil compressibility and thickness of soil

The calculating value of consolidation settlement using large-strain consolidation theory is rather accord with actual examples.
