Predicting Method of Surrounding Rock Deformation of Tunnel and Study on Safety

摘要：

Surrounding rock will be deformation because of double-arch tunnel excavated. When surrounding rock deformation exceeds critical deformation value, it will bring dangerous on stability and on safety. So it is very important that we study on critical deformation value and predicting method of surrounding rock deformation. This paper have got the critical deformation value and predicting method of surrounding rock deformation by numeral analysis of equivalent material simulating experiment data, monitoring measure data. The methods and critical deformation values have been tested and verified on actual tunnel engineering. It has important significance for tunnel engineering construction on safety.
