摘要
在砂井地基固结度计算中,土的固结系数是一个十分重要的参数,土的固结系数通常通过室内试验求得,但室内取得水平向固结系数制样比较困难。利用软基处理过程中孔隙水压力监测资料来推算软土的固结系数,并和室内试验加以对比分析,总结出二者之间的相互关系及变化规律,可供同类工程设计借鉴。
In the calculation of consolidation degree of sand drain ground, coefficient of consolidation is an important parameter. Normally we get the coefficient of consolidation by laboratory testing, but it is diffieult to prepare solid specimen for radial coefficient of consolidation. In the paper, the writer uses pore water pressure time curve on soft base treatment to calculate reckoning the consolidation degree of soft clay, analyzes by comparing with the laboratory test result, it summarizes their mutual relations and changes regularity. The result can be referenced for similar design.
