地下管线周边土体病害评估方法的研究

Study on Assessment Method of Surrounding Soil Disease of Underground Pipeline

地下病害对其周边地下管线的风险评估目的是识别出城市道路与管线周边地下病害可能给道路或管线运行造成的危害。根据本课题的研究目的,通过对风险评估方法进行分析、对比和筛选,最终选定采用层次分析法来完成研究本课题的风险评估方法。利用层次分析法,通过建立模型、构造判断矩阵等一系列步骤,最终得出了分层加权求和的评估方法。通过评估方法得出土体病害对周边关系的影响程度的等级,最终根据不同的等级采取不同的处治措施。

The purpose of risk assessment of underground diseases on the surrounding underground pipelines is to identify the hazards that may be caused to the operation of roads or pipelines by urban roads and underground diseases around pipelines.According to the research purpose of this topic,through the analysis,comparison and screening of risk assessment methods,the ahp method is finally selected to complete the research of this topic's risk assessment method.The evaluation method of layered weighted summation is finally obtained by a series of steps such as establishing a model and constructing a judgment matrix.Through the evaluation method,the degree of influence of soil diseases on the surrounding relationship is obtained,and finally different treatment measures are taken according to different grades.The research results of this project provide strong data support for the local standard of Beijing“code for evaluation and prevention of soil damage around underground pipelines”.
