摘要
Abstract
The author takes a project in the canal core area of Tongzhou district in Beijing as an example to explore the key con-trol points for reinforcement design of adjacent foundation pits when they both exceeds its service life of original foundation pit.The depth of the foundation pit with complex surrounding environment in plot 7 of the project is 14.75 m,and it has been in extended service over three years.The foundation pit with a depth of 21.90 m of plot 8 is on its east side,and there is an un-derground connecting passage between the two foundation pits.In order to ensure the smooth implementation of the under-ground connecting passage and the stability of foundation pit,it is necessary to develop a reinforcement design scheme.During project implementation,the whole process of foundation pit monitoring was carried out.The monitoring results showed that the scheme of backfilling reinforcement and prestressed anchors is safe and feasible in such complex environments,which can provide reference for foundation pit reinforcement with similar over-time service.关键词
