谈云母片岩大变形控制措施

Discussion on large deformation controlling measures of schist

结合具体工程实例,针对云母片岩大变形控制进行了探讨,分析了围岩大变形破坏的主要特征及原因,从施工角度入手,介绍了具体控制措施及施工工艺,指出施工过程中应加强工序衔接,快速有效的作临时及初期支护以确保施工安全及质量。

Combining with the specific engineering case,this paper inquires large deformation control of schist,analyzes main features and causes of surrounding rock deformation damage,introduces specific construction measures and construction technology by starting from aspect of construction,and points outs some measures in construction process,such as strengthening construction order connect,fast and effective temporary construction,and preliminary support,so as to guarantee construction safety and quality.
