同工况条件下不同静载方法在抗拔桩中的技术分析

在进行抗拔桩试验工程中,为了达到工程设计安全,需要进行静载荷试验,传统的锚桩法成本高,操作不方便,随着桩径、桩长的增大,其需要的反力也随之增大,而采用自平衡法进行静载荷测试,很容易增大反力,且具有操作方便、缩短工期、节省施工成本的优点,从两种工程实例得出结论,对于抗拔桩,传统锚桩法及自平衡法均可使用,但使用自平衡法效果更好。

Technological Analysis of Different Static Load Method in the Uplift Pile Under the Same Working Condition

In the uplift pile test engineering,in order to achieve safety engineering design we needed to carry on static load test,the traditional method of anchor pile cost high and its operation was not convenient,as increasing of the pile diameter and pile length the reaction has been increased. The selfbalanced method could be apt to increase the reaction,and has the advantages of convenient operation,shorten the construction period,saving construction cost. Conclusions from two engineering examples,the traditional method of anchor pile and self-balancing method all can use for the uplift pile,but using the latter is better.
