Study on Analysis Method of Safety of Reinforced Concretelining Based on ADINA

LIU Jie;YUAN Tengfei;TANG Liang;YAN Lizhou;China Three Gorges University;Collaborative Innovation Center for Geo-Hazards and Eco-Environment in Three Gorges Area,Hubei Province;  
Based on the New Austrian tunneling theory and permeable lining theory,using the ADINA finite element software,the ultimatebearing capacity of the concrete and steel lining as the criteria,the safety of lining under the external water pressure,internal water pressureand grouting pressure were analyzed and evaluated. Numerical analysis results indicate that:the concrete and steel in the lining of highlandstress and deeply buried water diversion tunnel of Danba Power Station under external water pressure and grouting pressure are in the fullycompressed state basic,the internal forces meet the requirements of carrying capacity;under the internal water pressure,lining meet therequirements of compressive bearing capacity,but is subject to greater tensile stress and the lining is easy to crack.
