塑料排水板处理吹填砂地基的试验研究

Experimental research on treating hydraulic fill sand ground with plastic draining plate

通过对吹填砂地基进行塑料排水板的现场监测和原位测试试验,从水位变化、孔隙水压力、水平位移情况、地基强度指标等各方面比较了两种不同工艺参数的处理方法的差别,并分析了产生差异的原因,对开展大面积的施工提出了必要的指导,提供了合理的参数.

According to the field monitoring and the in-situ tests of the plastic draining plate on the hydraulic fill sand ground, the differences between the two treatments with dissimilar technological parameters are compared from the aspects of water level variation, pore water pressure, horizontal displace- ment, ground strength index, etc.. The reasons of the differences are analysed; and a necessary guidance to the large-area construction is put forward; also the reasonable parameters are provided.
