复杂地层旁通道冻结施工过程的模拟与实测分析
Numerical simulation and measurement of freezing method applied to connected aisle in tunnel under complex conditions
采用冻结法修建地铁旁通道时，土体的冻胀和融沉量过大往往会造成地表隆起和沉降量过大，造成危害。因此，根据工程施工方法对施工过程进行模拟，预测土体的冻胀量和融沉量是非常有必要的。本文结合上海地铁某旁通道冻结法施工过程，采用FLAC3D对施工全过程进行了模拟，将模拟得到的地表位移与现场实测值进行了对比，结果表明模拟数据与实测地表位移变化量吻合较好。
Freezing method is used in the connected aisle of metro, the large displacement caused by frost-heave and thawing settlement of frozen soils would damage surround buildings. So, it is necessary to predict the frost-heave and thawing settlements by simulating the work progress based on method of construction. This paper predicted the surface displacement by simulating the whole construction process of a connected aisle in Shanghai metro by FLAC3D. Compared with the measurement, the results show that simulation data agree well with the measured.
