摘要
给出了碎石桩处理可液化地基土孔隙水压力比计算公式,并结合工程实际,考虑径向排水及垂向排水条件下,对孔隙水压力比进行计算,结果表明,经碎石桩处理后可液化地基土完全消除液化。
The calculating formula of treating liquefied soil foundation and pore water pressure ratio by broken rock pile is given in the paper.With a practical project, the ratio was calculated at the condition of the radial and vertical drainage.The result showed that the liquefied soil completely dispeled after the treatment of broken rock pile.
