偏压隧道的进洞施工扰动效应及安全监控
Disturbance effect of unsymmetrical pressure tunnel's entrance construction and safety monitoring
摘要
Abstract
The construction process of the road tunnel was numerically calculated in the method of numerical a-nalysis,and the resulting surrounding rock deformation laws and early supporting structure stress characteristics were studied. Combined with in - situ monitoring technology, and compared with surrounding rock' s deformation data, the process of tunnel construction was mastered dynamically, which provides the pasis for surrounding rock's classification adjustment, design parameters' adjustment of early supporting structure and secondary lining structure.关键词
