摘要
通过对气泡轻质土配合比进行验证分析,采用COMSOLMultiphysics仿真软件对地铁上方气泡轻质土填筑路基施工沉降进行模拟研究,并结合现场对地铁结构物变形监测和土压力分析及沉降观测,研究论证采用气泡轻质土进行地铁上方路基换填施工。
Through analyzingthe validated bubbles of proportion of light soil,the simulation study on the settlement of the construction of the subgrade filled with air bubble light soil above the subway is carried out by using the COMSOL multiphysics simulation software.And combined with the field of deformation monitoring of subway structures and soil pressure analysis and settlement observation,study demonstrates the bubbles of lightweight soil subgrade in fill construction above on the subway.
