某办公楼嵌岩桩的嵌岩深度分析

Analysis on the Pile Depth Embedded in Rocks of an Office Building in Haikou

分析了海口市某办公楼钻孔灌注桩的嵌岩深度及影响因素 ,试验分析表明 ,桩的长径比较大时 ,桩端阻力所分担的荷载仅占总荷载的一小部分 ,因而在满足施工质量的前提下 ,可适当减小桩的嵌岩深度 ,该工程桩设计嵌岩深度 1 5m ,实际采用了 0 8m ,加快了施工进度 。

Some factors and the depth embedded in rocks of pouring piles have been analyzed. The experiment illustrates that the resistance of the pile and undertakes only a small part of gross load when the ratio of the length to the diameter of piles is higher. With ensuring the quality of project, the pile depth embedded in pock can be reduced properly. The original design depth embedded in rocks was 1 5?m in this project, but we actually adopted the depth of 0 8?m and consequently speeded up project and cut down the cost.
