Abstract

Abstract:

A large amount of field measurement on surrounding rock stress of tunnel group on Hubei Section of ZhengzhouWanzhou Highspeed Railway with mechanized construction are carried out to learn the variation laws and distribution characteristics of surrounding rock stress of large crosssectional highspeed railway tunnel with mechanized construction. And then the surrounding rock stress variation laws and distribution characteristics of surrounding rock stress in Grade Ⅳ and Grade Ⅴ deepburied conditions are analyzed and compared with standard loads based on measurement results. The study results show that: (1)The stabilizing time of surrounding rock stress starts on the 21st to the 27th day. (2)The measured surrounding rock stress is less than the calculated load of deepburied tunnel in related railway design codes. (3)Under the condition of Grade Ⅳ depth, the lateral pressure coefficient is 1.2-2.4 times that of standard load. (4)Under the condition of Grade Ⅴ depth, the lateral pressure coefficient is 0.86-1.43 times that of standard load.

Key words: large crosssectional tunnel, mechanized construction, surrounding rock stress, lateral pressure coefficient, monitoring and measurement
