摘要
本文介绍了嵌岩旋挖扩底灌注桩的施工工艺原理和施工技术,并结合具体实例进行了工程验证,实践证明所采取的针对性施工措施是成功的,本文的有关技术方法具有很好的适应性,可供类似工程进行借鉴。
The construction methods of the rock-embedded under-reamed piles by rotary drills are introduced in this paper. Those methods are proved to be useful in the field of two foundation engineering projects. So, the technologies of the rock-embedded under-reamed piles by rotary drills can be used in similar projects.
