影响风化岩渗透性质的若干因素探讨

Study on factors affecting the permeability of compacted soft rock

本文对取自同一料场的两种强风化砂页岩料进行了不同击实制样方式 ,不同的 5mm以下细料含量和制备含水量条件下的渗透特性研究 .同时 ,用垂直加压大型渗透仪研究了此种土料渗透特性随上覆压力变化的特点 。

In this paper, the permeability characteristics of two kinds of sandy shale soft rock under the conditions of different compaction styly, content of fine sand (d<5mm) and content of water are experimentally studied. Furthermore, the permeability of compacted soil under different vertical pressure is also determined. The results help to clarify how the permeability influenced by compaction style, load condition and other factors.
