预制桩的加密作用对消除粉土液化的应用分析

On consolidation effect of precast piles on eradicating silt liquefaction

基于预制桩的加密效应机理,结合具体工程实例,通过预制桩施工前后静力触探试验和标准贯入试验的对比分析,研究了打入式预制桩的加密作用,结果表明预制桩施工后有效改善了粉土的物理力学性能,减小了土层液化。

Based on the consolidation effect mechanism for the precast pile, the paper undertakes the comparative analysis of static penetration test and standard penetration test before and after the precast pile, researches the consolidation effect of driven precast pile, and proves by the result that the precast pile construction can improve the physical dynamic performance of silt and reduces the soil layer liquefaction.
