摘要
Abstract
The construction risks occur easily in shallow buried tunnel, such as side collapse, tunnel roof fall, hill aspect cracks, deformation instability which are caused by geological, terrain and influence of the environ ment. The security,duration and environmental risk of Ning-An inter-city railway shallow tunnels are analyzed. Then, the risk assessment principles and steps of the improved fuzzy synthesis method based on AHP are intro duced. An analytic hierarchy model of shallow tunnel construction and the possibility judgment matrix depend ing on improved fuzzy number are established. Finally, the Zhongming No.1 Tunnel risk grade is determined through risk coefficient and the typical risk reduction measures are put forward, combining with tunnel charac teristics and risk assessment results.关键词
