摘要

In mountain area, the pipeline system is friable to multi-hazards, such as the rainfall induced flood and landslide, the deterioration of the pipe materials due to the erosive effects of soil, gas, waste water inside or outside of the pipe, and improper municipal construction, et al.. In the second one of a serial of papers of the risk analysis of pipeline in mountain area, the risk analysis models of rain-caused landslide and rain-induced flood are applied to evaluate the safety grade of the pipeline system. The extreme value distribution functions of the rain-induced flooding in different rainfall recurrence intervals are modeled by taking into account of the terrain feature and surface runoff of specific gully, and also the statistics of the rainfall records in recent 30 years in Chongqing. A comprehensive hierarchical model for the risk assessment of the pipeline, by taking into account of the multi damage modes of the pipe under multi hazards, is proposed. The application of the present model in Chongqing is given in the end to approve its practicability.
