| 摘 要： | 介绍一种适用于地下基坑围护的新型预制混凝土围护桩:预应力工字型桩。通过研究工字型桩受弯作用下桩身裂缝出现、发展情况及变形特征,分析其承载力及破坏特征。试验表明:预应力工字型桩满足规范要求的检验标准,有一定安全储备,但当桩身出现裂缝后截面刚度损失较大,对其抗弯性能有较大影响。

| Abstract: | Over these years,the prestressed concrete pile has been used in the project widely.This paper introduces a new type of fender pile.In this study,the cracks and deformation of prestressed concrete I-shape pile has been studied by the experimental,then the bearing capacity and the failure mode are analyzed.Through the experimental study,it is testified that the flexure bearing behavior of the pile satisfies for the requirement of the code and with the safety factor. |
