| 摘 要： | 随着我国城市化进程的加快，以及大型基础工程建设投入力度的加大，大型的水平定向钻穿越工程项目也越来越多，然而针对这类工程的风险评价却还不多。某大型天然气输气管道工程项目，投资多，风险大，事先进行风险评估十分必要。首先根据项目专家进行项目评估建立指标体系，然后结合模糊综合评价法和层次分析法各自的优点，针对该指标体系及专家所提供的评判数据，建立判断矩阵和隶属度矩阵并运用Matlab编程计算得权向量和隶属度向量，计算得出项目的风险值，得出相应的结论。

| Abstract: | It was only about two decades that horizontal directional drilling crossing was introduced into China as a type of trenchless technology, which was rapidly developed in this period. As urbanization was accelerated in China, and along with the intensity of large - scale infrastructure construction projects increased, more and more large - scale projects of pipeline crossing were carried, but risk assessments on these projects are still few. The paper introduced a large-scale gas pipeline project with large amount investment and serious risk; the risk assessment prior to project construction is necessary. Firstly index system was established based on the project evaluation by the experts, then the synthesis of advantages of fuzzy comprehensive evaluation method and AHP （analytical hierarchy process） was adopted and according to the evaluation data, the judgment matrices and membership matrices of this index system were built ; and the weight vectors and membership vectors were calculated by Matlab programming, risk value of the project was obtained and the corresponding conclusions was drawn. |
