Anchorage is a public service facility that relates to the safety of water traffic.The regulations on the scale and layout of waterways anchorage in the code are not yet detailed.Taking the anchorage layout scheme of the west waterway of Beijing-Hangzhou Grand Canal as an example,this paper summarizes the anchorage location principle,the anchorage calculation method and berthing management scheme,and analyzes the anchorage conditions of the plain restricted channel .It is concluded that the location of the plain restricted anchorage should mainly consider the anchorage habits of sailor and external traffic conditions.The combination of continuous structure and isolated pier structure in the restricted waterways of the plains can meet the requirements for the use of single ships and fleets,and it has a good economic advantage,and puts forward new ideas for the construction of restricted channel anchorages in the plains.It has positive reference significance for similar engineering construction and normative revision.
