摘要:
本文按照固结理论计算砂井的原理,作出了一整套诺模图,从而能用图解法很方便地确定砂井的设计方案,不必进行繁琐的计算工作;还能很方便地按不同的砂井方案获得最佳设计。特别是在厚度不等的软土地基中,当要求在同一时间内达到相同的固结度时,用一般的方法必须进行大量的计算,而用本文的图解法则能很方便地得出符合要求的最佳砂井设计方案。最后还给出了例题。
Abstract:
In this paper, a set of nomographs is designed to facilitate the planning of ground improvement by sand dralns according to the theory of consolidation of soil. Tedious numerical calculations are avoided and different plans of sand drains can be easily obtained, among which the optimum design is to be ascertained. When the soft soil layer to be improved is of varying thickness, in order to attain the same degree of consolidation during the same specified time interval, a large amount of calculations is required by the ordinary method, while it becomes quite simple by using the nomographs given. A numerical example is also given for illustration.
