静载试验在PHC管桩质量控制中的应用

Application of pipe pile static load test in construction quality control

依托某高速公路山涧软土地基处理工程,通过跟踪检测PHC管桩的单桩承载力,初步分析试验桩的施工控制参数与其承载力的对应关系,及时调整不同地质区域内的施工控制参数,确保了工程质量,为今后类似工程设计和施工质量控制提供了参考。

This paper leaned on the ravine soft soil base treatment project of a express way. According to tracing and testing the bearing capacity of single pile, a preliminary analysis of the relationship between construction control parameters and bearing capacity of a testing pile was made. The result of the analysis work were used for adjusting the construction control parameters of the other piles. This insured the quality of the base strengthen project, and the experience can be referred by other similar projects in designing and quality controlling.
