| 摘 要： | 近年来忠武输气管道山区段发生了多起危岩坠落危害管道的事件,已经严重威胁到输气管道正常运行。本文以恩施石马岭危岩为例,结合运动学和概率统计分析的模型,利用Rocfall软件对危岩运动情况进行了模拟,并在此基础上用两种方法计算了冲击力,对比分析了两种计算结果并指出了计算结果差异的原因。评价认为危岩坠落冲击将会对管道造成严重破坏,必须对危岩体进行治理。

| Abstract: | In last years,the rock fall harmed the natural gas pipeline in the mountainous area between Zhong County and Wuhan City,which has threatened the safety of the pipeline and transportation of gas.In the paper,based on the investigation of Shimaling dangerous rock in Enshi City and applying the theory of kinematics and probability model,the rock fall software was used to simulate the possible movement falling from the steep slopes.According to the results,we evaluated on the impact to the pipeline with two methods,and analyzed on the causations for the difference.The conclusion indicated that the rock fall would destroy the pipeline,so the dangerous rock should be controlled.With the research of Shimaling dangerous rock,the practical evaluation method is presented,and it has already been used in the evaluation of pipeline between Zhong County and Wuhan City. |
