| 摘 要： | 当前TBM在深埋隧洞施工中的应用越来越多，由变形引起的TBM施工事故也越来越普遍，因此很有必要对变形引起的TBM施工事故进行风险分析。采用收敛–约束法并结合风险分析理论，考虑洞室的掌子面和护盾后方支护的效应，对围岩作用在护盾上的压力进行计算；同时，根据作用护盾上压力大小判断洞室变形对TBM施工的具体影响，把事故的后果分为5个等级，根据后果等级结合发生的概率提出TBM施工变形风险评价矩阵，然后结合现有的风险接受准则即可确定风险等级。最后，采用研究成果对南水北调西线某段双护盾TBM施工进行风险评估。

| Abstract: | Tunnel boring machine(TBM) is widely used in deep tunnel at present;and the accidents caused by tunnel deformation become more and more common.Therefore,it is very necessary to analyze the risk of accidents induced by tunnel deformation in advance.Considering the mutual effect of tunnel face and shield rear support,convergence-confinement method and risk analysis theory are applied to calculate the pressure imposed by surrounding rock on shield.Meanwhile,according to the magnitude of pressure imposed on shi... |
