| Abstract: | Length of tunnels comprises 68.1% of the length of Lanzhou-Chonqing railway.In tunnels there exist four high risk resources such as,water-rich immature sandstone and large deformations of soft rock with high ground stresses;gas(natural gases);mud and water outburst in karst(worked-out area of coal mine),that seriously affect construction safety,progress and investment control.By means of on-site survey,expert consultation,construction testing and continuous optimization of design and construction,the main i... |
