摘要
本文以重庆轨道交通5号线大竹林停车场—重光站段区间为依托工程,建立梁-梁计算模型分析单护盾TBM在施工过程中的受力情况,该模型计算准确且更加方便提取接头内力,分析接头的受力情况,通过计算得到单护盾TBM接头结构的张开度,验算在施工荷载下接头结构防水也能满足要求。
This paper based on the Da zhu lin parking station~Chong guang station of Chong qing rail transit line 5engineering,we built the beam—beam numerical calculation model to analyze the influence on the TBM tunnel during the construction,and the model could be more accurate during calculation and was more convenient to extract the joint internal force,this paper analyzed the stress of the joints,single shield TBM joint structure's opening is obtained by the calculating,and we found out that the waterproof of the joint under construction load can meet the requirements.
