由于软弱粘土的沉积会延伸至相当的深度,所以就连给轻荷载结构物选择合适的地基类型也是困难的。本文介绍并讨论了在受控条件下设置于软粘土中的单根碎石桩和碎石桩群的模拟结果,通过单根桩的试验得出了桩周围土的含水量和桩长度与直径的比值的影响后,便把研究扩展到桩群。研究结果表明;碎石桩群可令人满意地提高软弱地层承载力2～3倍。
Because the deposition of soft clays extends to a considerable depth, it is difficult to choose the right type of foundation for light load structures. This paper introduces and discusses the simulation results of a single gravel pile and a gravel pile group set up in soft clay under controlled conditions. The water content of the soil around the pile and the length and diameter of the pile are obtained through a single pile test. After the influence of the ratio, the study was extended to the pile group. The results show that gravel piles can satisfactorily increase the bearing capacity of soft ground by 2 to 3 times.
