摘要

基于数值模拟方法，对厦门海底隧道施工进行优化分析。在侧压力系数为0.6和0.9情况下，首先针对3种常用施工方法——全断面开挖法、上下台阶法和台阶分部开挖法进行计算分析，通过比较隧道洞周关键点位移及洞周塑性区分布，得到全断面开挖对围岩的扰动较小；然后，通过计算分析不同台阶长度对隧道的稳定性的影响，得到上下台阶开挖台阶步距为10 m左右较为合理的结论，对海底隧道的施工具有一定的指导意义。

Abstract

Based on numerical simulation

the construction scheme of Xiamen subsea tunnel is optimized. Under conditions that lateral pressure coefficients equal to 0.6 and 0.9

firstly three common construction methods that are method of whole section excavation

scheme of upper and down benching and bench tunneling method are analyzed; the result that method of whole section excavation will slightly disturb the surrounding rock is gained compared the displacements of keypoints and the distributions of plastic zone on the surface of wall rock; finally the conclusion that the reasonable bench pace between upper and down benches is around 10 meters is proposed by analyzing tunnel stability under different bench lengths. The conclusion can direct the construction of tunnel better.
