摘　　要：为研究解决石家庄至太原高速铁路隧道断面有效净空面积标准、长段落膏溶角砾岩地层内修建隧道、特大断面隧道修建以及超长隧道(群)防灾救援系统设置等技术难题,通过采用调研分析、数值模拟、模型试验、现场试验段试验等一系列研究手段,确定了时速250 km高速铁路单线、双线隧道有效净空面积标准,顺利实施了高速铁路特大断面隧道到2条单线隧道的过渡,安全通过了长大段落膏溶角砾岩地层,创建了铁路特长隧道(群)防灾救援成套技术,最终实现了石太客运专线的顺利开通运营,并取得了良好的经济效益和社会效益。Key technologies for Taihangshan super-long high-speed railway tunnel group,including standard for the effective clear area of high-speed railway tunnels,tunneling in long-distance gypsum breccia section,construction of super-large cross-section tunnel and arrangement of disaster-prevention and rescue system of super-long tunnel group,are studied by means of literature survey,numerical simulation,model test and field trials. In the end,the standards for the effective clear areas of single-track and double-track tunnels on 250 km / h high-speed railways are determined,the transition from a super-large cross-section high-speed railway tunnel to twin single-track tubes is achieved,the tunneling through long-distance gypsum breccias is accomplished,the disaster-prevention and rescue system of super-long tunnel group is determined,Shijiazhuang-Taiyuan high-speed railway is put into operation successfully,and good economic and social significance is achieved.
