结合青藏±400 kV格尔木换流站工程的实例,介绍了振冲碎石桩的设计方法和桩基检测效果。结合规范,对振冲碎石桩设计参数的确定进行了分析,并对复合地基承载力的计算方法进行了探讨。通过对桩基检测的各项数据进行分析,对地基处理的实际效果进行评价,指出对于加固站内粉细砂地基,振冲碎石桩的应用是成功的,具有加固效果好、速度快、投资少等优点,达到了预期的地基处理的目的。
Combined with the example of Qinghai-Tibet ± 400 kV Golmud converter station, the design method of pile and the effect of pile foundation are introduced. In combination with the specification, the determination of the design parameters of the vibration-assisted stone column is analyzed, and the calculation method of the bearing capacity of the composite foundation is discussed. Through the analysis of the data of pile foundation testing, the actual effect of foundation treatment is evaluated. It is pointed out that the application of vibro replacement stone pile is successful for the fine sand foundation in the reinforcement station. It has the advantages of good reinforcement effect, high speed, Less advantages, to achieve the purpose of the expected foundation treatment.
