关于堆载预压法所堆荷载量的研究

Discussion on the Principle of Weak Ground Treatment with Preloading

讨论了堆载预压法处理软基的根本原理,说明了堆载法处理软基的根本原因是能减少建(构)筑物修建后引起的沉降.因此在承载力满足要求的条件下沉降变形是堆载预压法处理软基的控制因素,只要建(构)筑物修建后所引起的沉降变形满足上部结构的要求即可,卸载量并非一定要大于或等于上部结构荷载量.

This paper discusses the principle of weak ground treatment with preloading, and explains that the reason of treating weak ground with the method of preloading is that it can reduce the settlement, which arises with the construction. So on the condition that the bearing capacity is enough, deformation is the controlling factor. If the settlement, which arises with the construction, meets the need of the construction, the unloading quantity is not definitely more than or equivalent to the load of construction.
