浅海复杂管线(管道)探测的综合物探方法研究
|
摘要
中央和各地政府近年来大量规划建设外海岛屿过海供水管道,需要对沿途大量的海底管线(管道)进行调查梳理,为设计施工方案提供依据。目前海底管线(管道)类型丰富,物化特性各异,安装条件也差别很大,给探测方法的选择和实施带来了很大困难。文中提出针对不同类型管线(管道)和工况采用多种方法联合探测的方式,在分析各种方法功能、优势和运用条件的基础上,采用综合分析评判方法达到准确探测的目的,并将该方法运用到舟山某跨海供水管道工程沿途既有管线调查中,结果表明该方法在可行性、准确性、全面性和系统性方面优势明显。
In recent years, the central government and local governments have planned and constructed a large number of offshore island water supply pipelines, during this procedure it needs to investigate and sort out a large number of submarine pipelines along the way, so as to provide a basis for the design and construction scheme. At present, the types of submarine pipelines are abundant, the physical and chemical characteristics are different, and installation conditions as well, which brings great difficulties to the selection and implementation of detection methods. Based on the analysis of the functions, advantages and operating conditions of various methods, a comprehensive analysis and evaluation method is used to achieve the purpose of accurate detection. The method is applied to the pipeline investigation of a cross-sea water supply pipeline project in Zhoushan. The results show that the method has obvious superiority in feasibility, accuracy, comprehensiveness and systematicness.
