桩和既有基础联合使用进行工程支护的探讨与尝试

An Attempt to Support Hollow Engineering By Using The Existing Foundation in Alliance With Piles

根据某项改建工程的要求，采用了双排砼灌注桩与既有基础加箍后用于工程支护的方法，从而来保证既有建筑物基础不发生变形和基坑开挖时边坡的稳定．桩和既有独立基础联合使用，在该项工程中得到了完全实施。

In line with the need of reconstructing engineering, the method of pile and hoop existing foundation was adopted to support the structure. In this way the existing structure basis was guaranteed against the occurrence of transforming shape and dislocation of boundary while the hollow was being dug. The method of using the existing foundation in alliance with piles was employed in this engineering, and was very effective.
