高井2号住房 CFG 桩复合地基受地铁振动影响分析

摘要

The 2# housings in Gaojing have been affected by the vibrational loading of the subway. Based on the existing stratigraphic informa-tion,the FLAC-3D geological model has been made to analysis the influence of the vibrational loading to the Cement Fly-ash Gravel. The velocity and deformation of the Cement Fly-ash Gravel have been calculate. The calculation results and the measured results are basically identical through the contrastive analysis of the two results.%结合已有的地层资料，建立 FLAC-3D 模型对高井2号住房受地铁振动影响进行模拟，分析了车辆行驶情况下，地铁振动对CFG 桩影响程度，并计算了 CFG 桩的变形和速度，将计算结果与实测结果进行了对比分析，得出计算结果与实测结果基本一致的结论。
