摘要
Abstract
It is inevitable that tunnel construction will cause certain terrain movement nearby. Tunnel passing underneath existing railway can lead to uneven subgrade settlement, affecting the normal operation of the railway. Taking the underneath railway in a new metro region as the object of study, MIDAS GTS software for numerical simulation is used to analyze the construction process, which focuses on the reinforcement effect of different grouting radius on terrain when half-section deep-hole grouting is adopted for the tunnel. On the premise of safe construction and operation, as well as economical rationality, the reasonable grouting range (radius) for reinforcement and the measures ensuring normal operation are proposed.关键词
