| Abstract: | The Eling Tunnel, with a length of 10455 m and a maximum depth of 750 m, is located in the Jinggangshan area, Southern Jiangxi Province. It is a key engineering structure along the newly built railway from Hengyang to Chalin and to Jian. Folding and fracturing structures through the Eling Tunnel are considerably complex and brittle fractures such as joints and cleavages are commonly filled with water. The water inflow is a key engineering parameter for the design and construction of a tunnel. On the basis of regional-scale engineering geological and structural investigation, several petrological domains with different degrees of water penetration were used to test the drilling-wells and hydrological geology. By means of aforesaid work, abundant first-hand data of tunnel engineering and hydrological geological condition were obtained. The authors carefully analyzed these data related to the tunnel engineering, and identified important parameters for each petrological domain including water inflow (m3/d.km) and penetrating-water factor (m/d.km). Then, we divided the tunnel into nine sub-blocks according to |
