天津市堆山造景工程地基稳定监测与防治

Monitoring and control of foundation stability of a construction site on waste disposal area in Tianjin City

堆山造景工程是一项利用建筑渣土,在坑塘上进行堆载的市政工程。通过对堆山造景工程的工程地质条件分析,结合工程设计、施工工期等条件,提出了清理淤泥、设置反压平台、排水、控制堆填速率等促进地基稳定的防治措施。利用孔隙水压力监测、侧向位移监测及分层沉降监测等原位监测数据,以复合型法进行反演力学计算参数,并将反演结果用于该工程地基稳定性的模拟,以指导后期工程以及类似工程的建设。

The construction waster of the city was gathered to fill the pond. In this paper, the authors introduced the engineering geology, design and time limit of the project of piled mountain, put forward some prevention and cure measures to improve the groundsill stability, including clearing silt, mounting stress platform, accelerating drainage, controlling piled velocity, and so on. Based on the in-situ monitoring data of pore water pressure, horizontal displacement, ground subsidence, we calculated the stability of the site.
