浅谈流砂地基的处理方法

Solving Problems When Sand Ground is Partly Deepened

根据流砂形成的原因,一般的施工方法是通过降低地下水位来减小动水压力,控制流砂形成的原动力防治流砂。本文论述了根据特定的施工地质条件从另一角度出发,不降水,而是在细砂中掺入一些粗砂、碎石等,改变砂土粒度级配来治理流砂。之后借助水撼等施工方法加固地基,同样会取得经济有效的结果。

According to the cause of drift sand formation an ordinary construction way to pressure by lowering water - table. In terms of certain construction geological condition, the paper presents a different construction way to prevent drift sand by increasing drift sand pressure and changing sand size distribution and to reinforce the ground by shaking sand, which can achieve the same effective result.
