粉喷桩复合地基的优化设计方法探讨

本文通过对常规的设计方法(以承载力为主控指标的设计方法)和以沉降量为主控指标的设计方法对比。重点讨论以沉降量为主控设计方法及其有关因素对沉降量的影响,明确了以沉降量为主控指标的设计方法从理论、经济上均优于常规的设计方法,同时对粉喷桩复合地基优化设计提出了新的设计思路和建议。

In this paper,we compare the conventional design method （the design method of which bearing capacity is the primary control factor） with the design method of which settlement is the primary control factor. Then,we draw a conclusion that the latter is superior to the former from theoretical and economic aspects.At the same time, we propose new design ideas and suggestions for optimization design method of DIM pile composite foundation.
