隧道二衬混凝土开裂现象在隧道施工中时有发生，尤其是在不受外力作用时形成裂纹的原因更是让建设者难以处治。就背景工程出现类似问题，通过理论计算与数值模拟，探求混凝土结构本身的受力情况，结合施工工艺、施工环境、混凝土养护、施工干扰等方面因素，对混凝土开裂问题进行系统分析，找出开裂原因，为建立相应处治措施提供参考。
隧道二襯混凝土開裂現象在隧道施工中時有髮生，尤其是在不受外力作用時形成裂紋的原因更是讓建設者難以處治。就揹景工程齣現類似問題，通過理論計算與數值模擬，探求混凝土結構本身的受力情況，結閤施工工藝、施工環境、混凝土養護、施工榦擾等方麵因素，對混凝土開裂問題進行繫統分析，找齣開裂原因，為建立相應處治措施提供參攷。

The crack of tunnel secondary lining concrete occurs in the tunnel construction every now and then.Especially for the crack formed not affected by external force,it is more difficult to tackle the issue.As similar problems appear in some engineer project ,we ex-plored the stress condition the concrete structure itself held by means of theoretical calculation and numerical simulation.Combined with the construction technology,construction environment,concrete curing,disturbance and so on,we finally systematically analyzed the con-crete crack problem,found out reasons for cracking and provide a reference for establishing corresponding treatment measures.
