摘要
通过对某围垦工程海堤地基土体在塑料排水板施工前,及施工结束后取样进行各类土工试验分析,从土体工程特性变化的角度,对比了土体的含水量W、孔隙比e、压缩模量Es、固结系数Cv、快剪及固结快剪C、φ值等物理力学性质参数,其性质均得到了很大的改善,从另一个侧面说明,以塑料排水板为主要排水设施的排水固结法处理海相沉积软土是有效的。
Through the soil test analysis before and after the plastic drainage wall installated in foundation treatment of a reclamation project, it compares the soil moisture content W, void ratio e, compression modulus Es, coefficient of consolidation Cv, fast cutting, and consolidation of fast shear C, φ values of other physical parameters of mechanical properties , from the soil engineering characteristic changes, its nature have been greatly improved, which shows plastic drainage wall as the main drainage facilities is effective measure for consolidation of the marine deposits of soft soil.
