桩基静载试验中锚桩对试桩承载力影响研究

Research on Influence of Anchor Pile on Bearing Capacity of Test Pile in Static Load Test for Pile Foundation

基于锚桩加载法承载力现场试验工程实例,通过建立有限元模型,并与试验实测结果进行对比分析,得出了锚桩的布置形式、锚桩与试桩距离大小、锚桩直径大小等因素对试桩极限承载力的影响规律,对指导锚桩法在桩基静载试验中的应用具有重要意义。

Basing on the engineering project of bearing capacity field test for anchor pile loading method, the contrastive analysis on actual measurement results of test is made by building a finite element model, and the influence rule of factors like layout form of anchor pile, distance of anchor pile and test pile, diameter of anchor pile and etc. on the ultimate bearing capacity of test pile is obtained, so as to provide important significance for guiding the application of anchor pile method in static load test for pile foundation.
