摘要
福建沿海地区地质情况较为复杂,其软土地带均属陆海相沉积,常采用振动沉管桩方式作为建筑物的工程桩,但该软土层压缩性较高,常因施工及设计不当出现缩颈、离析、断桩等问题,笔者通过某工程施工质量事故结合桩低应变反射波法检测和静载检测结果,分析其施工中质量问题及其原因,并提出相应的防治措施。
Due to the complex geological formation and the high subsidence degree of deep soft soil in Fujian coastal areas, vibrosinking grouting piles are commonly adopted as construction foundations. Possible problems causing the quality accidents of pile foundations are analyzed and some appropriate prevention measures are proposed.
