摘要
本文改进了真空预压砂井地基固结分析半解析方法,使它也适用于堆载预压和成层地基情况。其计算简便,对加固面积和砂井根数无限制,可考虑土的粘弹性、固结三向性、砂井群共同作用、井阻和涂抹的影响。改进后侧向位移计算结果的精度比原方法有很大提高。
The Semi-analytic method for vacuum preloading of a foundation with sand drains is improved in this paper, so that it can be also applicable to the case of surcharge preloading and multiple layered foundation. The Computation is simple and the area of improvement and the number of sand drains are not confined. This method takes into account the effect of clay viscoelasticity, 3-D consolidation, sand drain group, well resistance and smear. The calculated results of lateral movement of the improved method are checked more fairly well with field measurements than those of the unimproved ones.
