基于 MIDAS／GTS 的高压隧洞渗流场与应力场耦合分析

摘要

MIDAS/GTS is a finite element analysis software for geotechnical and tunnel.By use of this software, coupling analysis of seepage field and stress field of tunnel with high-pressure is numerical simulated, which combined with Huizhou Pumped Storage Power Station in Guangdong Province.According to comparative analysis with other program’s results, the reliability and practicality of MIDAS/GTS are verified.It can be applied to similar projects in coupling analysis of seepage field and stress field of high-pres-sure tunnel.%MIDAS／GTS是针对岩土和隧道的有限元分析软件，利用该软件结合广东省惠州抽水蓄能电站工程，对高压隧洞渗流场与应力场耦合分析进行了数值模拟，并与其他程序计算结果进行了对比分析，验证了MIDAS／GTS软件计算结果的可靠性和实用性，可将其应用于同类工程渗流场与应力场耦合分析中。
