摘　　要：用实测水文地形资料对比手段,从水文年的年际年内变化结合深泓线的摆动和变化特点入手,对钱塘江尖山河湾治江围涂前后的河势演变特性进行了分析,初步揭示了该河湾的演变规律。在此基础上,对河湾西南岸的建港条件作了初步探讨,分析表明河湾西南岸兴建港口的时机日渐成熟,并提出了可兴建开敞式专用码头和闭合式港池码头两种型式,运输船舶宜采用浅吃水肥大型船型,针对涌潮强、潮差大的河口地区,建议船舶采取"三乘、三避"的运作方式。By contrastive analysis on evolution characteristic of river and water depth condition of Jianshan bend of Qiantang estuary former and after river-training and polder Engineering,the paper makes a analysis and discussion on port construction on shouthwestern bank of Jianshan bend of Qiantang estuary. It is shown that the opptunity of port construction on shouthwestern bank of Jianshan Bend of Qiantang estuary are becoming increasingly ripe. It presents two kinds of port to construct,viz open port and close basin port. The ship should adopt shallow-draught and roomy type. The paper suggests the operation pattern of making use of high tide level,and evading tidal bore, rapid flow and low tidal level.
