摘　　要：在进行地下空间设计以及施工过程中,对地质情况和开挖是否存在风险进行有效评估是十分有必要的。文章以某一隧道施工时出现的围岩大面积变形而造成支护体系和衬砌遭到破坏为例,对隧道软弱围岩变形预测方法进行了分析,对隧道的地质以及水文条件进行了详细调查,修订了施工图纸的变形等级,并对围岩变形采取了有效的控制措施。隧道后期的开挖中,没有出现围岩变形现象,证明措施有效。It is necessary to effectively evaluate the geological conditions and excavation risks during the design and construction process of underground spaces.The article takes the large-scale deformation of surrounding rock during the construction of a certain tunnel,which caused damage to the support system and lining,as an example to analyze the prediction method for the deformation of weak surrounding rock in the tunnel,conduct a detailed investigation of the geological and hydrological conditions of the tunnel,revise the deformation level of the construction drawings,and take effective control measures for the deformation of surrounding rock.During the later excavation of the tunnel,there was no deformation of the surrounding rock,proving the effectiveness of the measures.
