摘要
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。
Based on an engineering example of the ±400 kV Golmud Converter Station of Qinghai-Tibet Intereonnection Project, this paper introduces the design method and pile test results of the vibratory crushed stone pile. In light with the design code , the paper analyzes determination of the design parameters of the design and discusses the calculation method for the carrying capacity of the composite foundation. Through analysis of all the test data, the real effect of the foundation treatment is evaluated. It is concluded that, for reinforcement of the fine sand foundation in the substation, the use of the vibratory crushed stone pile is successful, as the pile has advantages of good effectiveness, fast speed, and less cost, and it can achieve the desired purpose of foundation treatment.
