摘　　要：以剪切波速法为基础,总结以往判别方法的缺点,结合已有的研究资料,同时考虑碎石桩的排水效应和减震效应,给出了实用的碎石桩复合地基液化判别方法。该判别方法充分考虑了碎石桩的各种效应,较真实地反映了处于实际工作状态时碎石桩的潜在作用。Based on shear wave velocity method, combining with the defect of existing discriminating methods and the existing research data, at the same time considering the drainage effect and cushion effect of gravel piles, the practical anti-liquefaction discriminating method of gravel piles composite foundation is presented. This discriminating method considers different effects of gravel piles and reflects potential function of gravel piles under actual working condition.
