倾斜PHC管桩的处理方法及剩余承载力研究

已完成施打的PHC管桩,由于疏于保护等因素,使桩承受了非能预见的水平荷载,桩身通常会出现一定程度的倾斜,它会使PHC管桩桩身产生裂缝、断裂、弯曲或倾斜,使PHC管桩承载力降低或者失效,对工程质量及安全产生重大的影响.通过某工程的PHC管桩受基坑滑坡影响造成倾斜处理实例,从现有理论分析成果出发,结合工程实际处理的对策,得...

Study on Treatment Method and Residual Bearing Capacity of Inclined PHC Pipe Pile

The completed PHC pipe pile bears the unforeseen horizontal load due to lack of protection and so on. The pile body usually inclines to a certain extent, which will cause cracks, fracture, bending or inclination of the PHC pipe pile body. As a result, the carrying capacity of the PHC pipe pile is reduced or failed. Thus has a significant and negative impact on the project quality and safety. With the example of PHC pipe pile slope treatment caused by foundation pit landslide in a certain project, based on the existing theoretical analysis results and combined with the countermeasures of engineering practice, the conclusion with guiding significance for the engineering practice is obtained, which provides an effective scheme for the treatment of similar engineering defective pile.
