摘要
通过数值模拟分析某住宅项目的深基坑及基础工程施工对临近在营地铁结构的安全性影响,获取地铁结构在项目基坑及基础施工过程10个工况下的变形及内力值。计算结果显示该项目施工过程产生的累计最大变形及内力值对地铁结构的安全性无影响,证明基坑及基础工程设计方案合理可行。结合地铁结构现状调查、仿真数值模拟、施工过程地铁结构变形监测及相关保障措施,可以使地铁结构变形量控制在合理范围内,达到保护地铁结构安全的目的。
Analyzing the safety impact of the deep foundation pit and foundation construction of a residential project on the nearby operating subway structure by numerical simulation,and the deformation and internal force value of the subway structure under 10 working conditions of the foundation pit and foundation construction process are obtained.The calculation results show that the cumulative maximum deformation and internal force value generated by the construction process have no impact on the safety of the subway structure,which proves that the design scheme of foundation pit and foundation engineering is reasonable and feasible.Combined with the investigation of the current situation of subway structure,numerical simulation,subway structure deformation monitoring during construction and related safeguard measures,the deformation of subway structure can be controlled within a reasonable range and achieve the purpose of protecting subway structure safety.
