Paper Title:
Comparative Analysis of CRD Method and Three-Bench Method with Temporary Invert
  Abstract

CRD method and three-bench method with temporary invert, which are applied to shallow buried and large cross-section tunnel engineering, are discussed, and simulated by FLAC2D so as to study the variation feature of displacement field, surrounding rock disturbance and internal supporting force caused by the excavation. According to the simulation results, it is proved that CRD method, with higher safety, can control tunnel collapse effectively while three-bench method quickens construction schedule. Therefore, it is recommended that the two methods are used for excavating tunnels alternately if possible so that it will increase economic benefit.
