Risk Assessment on Ground Fissure Disasters of Xi’an Metro Line 3
Due to special geological environment in Xi’an, serious ground fissure disasters will occur to the Metro construction. According to the planning, Metro Line 3 will meet with the ground fissures at 15 segments. Based on the results of model test and numerical analysis, the minimum sedimentation value of ground fissure arousing disasters on metro was determined as . By using the evaluation model of risk degree as R = P×V, risk degrees of each segment where the metro crossed ground fissures was calculated. The results showed that in normal design circumstances, there are eight ultra-high risks segments and two high risks segments. Therefore, special measures should be taken to reduce risks for these segments with high risks or above.
