- W2380761714 abstract "Taking the loess tunnel constructed by bench method of Lanzhou-Chongqing Railway as background,the engineering characteristics of the surrounding rock in loess tunnel were analyzed by triaxial consolidated-drained shear test and the construction process of tunnel was simulated by FLAC3D.Bilinear strain-hardening/softening ubiquitous-joint model was selected to simulate the engineering characteristics of the surrounding rock in loess tunnel as well as to study its longitudinal displacement.Results show that the structure of the surrounding rock in loess tunnel is broken by tunnel excavation disturbance.The Mohr failure envelop of the surrounding rock in loess tunnel is double linear broken line.The vertical joint of surrounding rock is all over developed in loess tunnel.The longitudinal displacement of the surrounding rock at side wall is smaller than that at the crown as a whole.The preexisting longitudinal displacement of surrounding rock takes up about 33%~41% of the total longitudinal displacement.Along with the advance of tunnel face,the longitudinal displacement of surrounding rock tends to be stable.The reserved core soil can effectively control the development of the longitudinal displacement and the plastic zone,which is beneficial to tunnel face stability and construction safety.The influence scope of tunnel face space constraint is-4R~4R(R is the equivalent radius of tunnel excavation).Using the bilinear strain-hardening/softening ubiquitous-joint model,the prediction of the preexisting longitudinal displacement of surrounding rock agrees with the existing theoretical result.However,it can better reflect the engineering characteristics of the surrounding rock in loess tunnel." @default.
