郑州某粉煤灰场地预制管桩承载性能研究

Study on Bearing Capacity of Precast Pipe Pile on Flyash Foundation in Zhengzhou

介绍郑州某场地粉煤灰的工程性质,通过采用静载荷试验对实际工程中预制管桩的成桩质量进行检测,根据现场静载荷试验中记录的p～s曲线,进一步分析研究粉煤灰场地的桩基承载能力,证明了在粉煤灰场地施工预制管桩基础的可行性。

The engineering property of the flyash foundation in Zhengzhou was introduced and the quality of PHC pile was tested by the static load test.According to the p～s curve in the static load test,the bearing capacity of pile on the flyash foundation was studied.Then its feasibility on the flyash foundation and the rationality of the standard value of ultimate lateral resistance of pile on the flyash layer were discussed.
