摘要
受潮流和径流影响,闽江河床地形不断冲淤变化,为研究盾构施工引起的河床变形情况,采用水下机器人、多波束测深技术进行水下地形数据采集,与Mike21确定的洪、潮作用下河床变形预警值对比,分析河床实时变形情况,为盾构安全施工提供参考数据,该研究方法可为类似过江隧洞的施工提供借鉴。
Affected by the tidal and runoff,the riverbed topography is constantly changing with erosion and deposition.To study the riverbed change caused by shield construction,this paper adopts underwater robot and multi-beam sounding technology to collect underwater topographic data,and compares the riverbed change determined by Mike21 under the action of flood and tide to analyze the real-time changes,so as to provide reference data for the shield construction The research results can provide reference for similar shield construction projects.
