摘要：

为应对我国山地管道面临的严峻地质灾害风险,解决现有防护技术系统性不足的问题,有必要构建一套科学的管道地质灾害防护技术体系。通过整合风险识别、评估、监测预警和工程治理4大核心技术模块,建立多平台协作的综合性防护框架;以贵州尧龙山段管道滑坡为案例,采用野外调查与有限元数值模拟相结合的方法,验证该体系的风险评估功能。结果表明,该管道的失效判据指数均小于1,无失效风险。所构建的技术体系可为管道地质灾害防治提供系统性的解决方案;该案例的具体数据能够为该区段管道的监测巡查与工程治理提供明确的科学依据。

Abstract:

To address the severe geological disaster risks facing pipelines in mountainous regions of China and overcome the lack of a systematic approach in existing protection technologies, a scientific and systematic technical system for geological disaster prevention along pipelines was developed. By integrating four core technical modules, risk identification, assessment, monitoring and early warning, and engineering mitigation, a comprehensive protection framework based on multi-platform collaboration was established. By taking the pipeline landslide in the Yaolongshan section of Guizhou as a case study, the risk assessment function of this system was validated through a combination of field investigations and finite element numerical simulations. Research indicates that the integrated protection system represents a trend toward multi-technology and multi-tier integration in disaster prevention and control. The results indicate that all failure criterion indices for the landslide are less than 1, indicating no risk of failure. The developed technical system provides a systematic solution for geological disaster prevention in pipeline engineering. The specific data from the Yaolongshan case offer clear scientific support for monitoring, inspection, and engineering mitigation of pipelines in this section.

Key words: geological disaster related to pipeline, protective technology system, risk assessment, monitoring and early warning, failure criterion
