- Abstract
As for the safety of oil depot, the safety of diversion tunnel is very important. In this paper, the safety of oil depot diversion tunnel is regarded as the research object, and the main factors which impact the oil depot diversion tunnel are analyzed. Take the safety of diversion tunnel in the earthquake as an example, the standard working conditions of 8-degree design intensity and III-grade surrounding rock in the earthquake are subject to numerical modeling and calculated by FLAC3D to obtain the displacement of vault and stress value under different buried depth. On this basis, a large number of samples can be obtained by Monte Carlo method, reliability analysis is conducted in two aspects of displacement and stress value, and the reliability of the oil depot diversion tunnel within 0-7 seconds under different buried depth in the earthquake can be calculated. According to the calculation result, the functional effects of diversion tunnel under different buried depth, the major damage nodes during the earthquake, the impact of earthquake stress on the diversion tunnel structure, and the damage effects of earthquake vertical and horizontal waves on the diversion tunnel can be obtained.
