摘要
为顺利推进盾构施工进度,基于现场的无水卵石地层的分布特征、地层强度以及土层参数等工程地质特征,运用FLAC^(3D)软件进行数值模拟盾构开挖过程,得出盾构开挖穿越该地层对沉降产生影响,并以此做出沉降曲线来进行深入分析,并提出改进措施。
In order to keep up with shield construction progress, based on the stratigraphic distribution chara-cteristics, stratum force index and soil -layer parameters of waterless sandy cobble stratum, this article uses FLAC ^3D numerical software to simulate the shield excavation process, and concludes that shield excavates this stratum will have influence on subsidence of ground surface. Based on this, we make a subsidence curve for in - depth analysis, and put forward improvement measures.
