摘要
海底输气管道须承受海底环境的变化,如发生管道安全事故,将带来巨大的损失.通过方案设计、资料收集、现场调查、样品采集、实验室测试、资料分析整理等工作,分析海底管道路由走廊区域范围内的海底沉积物类型及其分布情况,同时通过图件比对、数据分析,研究路由区海岸岸线和海床的变化特征,判断项目区海底底质的稳定状态,为管道工程设计、保护方案选择提供基础资料,以保证管道在海底长期运行中的稳定性.
Abstract
The submarine gas transmission pipeline must withstand the changes of the submarine environment.If a pipe-line safety accident occurs,it will bring huge losses.During the work,the types and distribution of submarine sediments within the submarine pipeline route corridor area are analyzed through scheme design,data collection,field investigation,sample collection,laboratory testing,data analysis and sorting,etc.At the same time,the change characteristics of the coastline and seabed in the route area are studied through map comparison and data analysis,and the stability of the sea-bed in the project area is judged,which is helpful for pipeline engineering design The selection of protection scheme pro-vides basic data to ensure the long-term operation stability of the pipeline on the seabed.
