浅析大口径灌注桩的受力机理

The Analysis of the fore mechanism of the large diameter cast-place pile

桩的受力机理 ,存在有“剪切破坏”和“刺入破坏”两种不同的理论解释。本文根据厦门地区 10根大口径灌注桩静载试验资料 ,通过对桩的轴向力的斜率变化特点分析 ,探讨并论证了“刺入破坏”理论的解释依据。

There are two explanation on the behavior mechanism:shear failure and punching failure On the basis the load pile test data of the large diameter cast-place piles in Xiamen;After careful studies of large pile axial force slope ,this paper test for explanation theory of pile punching failure.
