摘要
为了优化盾构管片开孔临时支撑系统,依托以色列特拉维夫绿线项目,对新型环形钢支撑支护形式进行了数值模拟理论分析。验证了此结构样式具有良好的结构稳定性、经济性、便捷施工性,可为类似管片破除临时支护或者管片加固提供一种新的解决方案。
To optimize the temporary support system for tunnel segment openings,a new type of circular steel support was analyzed by numerical simulation based on Tel Aviv Green Line project.It is proved that this structure style has good structural stability,economy and convenient construction,and can provide a new solution for similar temporary support or segment reinforcement.
