普通和高性能排水板在海堤施工中的效果对比分析

Comparative Analysis on the Effect of Ordinary and High-performance Drainage Board in Seawall Construction

海堤一般修筑在深厚的软土地基上,施工中常打设排水板加固软土地基。针对海堤施工中普通排水板和高性能排水板的复合体及滤膜进行对比分析,同时在整个预压过程中对采用2种排水板处理的地基进行4次取样检测及十字板剪切试验,并对试验成果进行分析研究,得出了在处理的初期高性能排水板区块土体的物理指标及强度增长比普通排水板更显著;同时,随着深度的增加,高性能排水板区块土体十字板强度及地基承载力增长更明显。

Seawalls are generally built on deep soft soil foundation,and drainage boards are set up usually in the construction to reinforce soft ground.The composite and membrane of the ordinary and high- performance drainage board were comparatively analyze in detail during seawall construction.Throughout the pre- press process,4 sample testing and vane shear test were carried out to the foundation,which was treated by using two kinds of draining board.The test results were analyzed.It was concluded that the physical indicators and strength growth of high- performance drain tile soil was more significant in the early treatment compared to that of ordinary drainage board.Meanwhile,as the depth increased,vane strength and bearing capacity of foundation of high- performance drain tile soil grew more obviously.
