摘要
锚泊区是内河平原航道的重要配套工程,主要包含船舶停泊水域及系靠泊设施。目前内河平原航道锚泊区多采用重力式结构。传统的重力式结构混凝土用量大、造价较高,且由于干地施工需求,局部航段需设置施工临时围堰。内河平原航道多同时承担防洪、灌溉、排涝任务,河道中建临时围堰施工工期长,汛期影响防洪。针对传统锚泊区结构形式存在的问题,以京杭运河济宁至台儿庄(济宁段)航道"三改二"工程为例,创新地采用趸船浮式结构和高桩墩式结构。与传统的重力式结构相比,该结构无需临时施工围堰,可水上施工,更有利于河道行洪,对地基适应性强。为内河平原航道锚泊区结构形式的选择提供了新思路,对类似工程的建设具有借鉴意义。
The anchorage area is an important supporting project of the inland river plain channel, mainly including the waters where ships are moored and mooring facilities. At present, the gravity structure is often used in the anchorage area of the inland river channel. The traditional gravity-type structure needs a large quantity of concrete and high cost, and a temporary cofferdam should be installed in the local navigation section to meet the demand of dry land construction. The inland plain waterway mostly undertakes tasks of flood control, irrigation, and drainage at the same time. The construction period of temporary cofferdam in the river is long and affects flood control during the flood season. In view of the problems existing in the traditional anchorage structure, the pontoon floating structure and high-piled pier structure are innovatively adopted in the "three-to-two" navigation channel project from the Grand Canal Jining to Tai’erzhuang district(Jining section). Compared with the traditional gravity structure, it can be constructed on water and does not need temporary construction of cofferdam. Meanwhile, it is more favorable for the river flood discharge and has better adaptability to the foundation, which provides a new idea for the selection of the structural form of inland waterway anchorage area and may serve as a reference for the construction of similar projects.
