本文阐述了钱塘江通海航道的现状,指出仓前至尖山的中段航道影响着河口出海通航能力,四工段浅滩是主要的碍航浅滩。文中还对不同水文条件下,钱塘江河口段的乘潮保证率和最大可能出海运量作了分析,在此基础上提出了改善航道条件的措施。
This article expounds the status quo of the Qiantang River passage and points out that the middle section of the warehouses to Jianshan affects the navigable ability of the estuary to go to sea. The four-section shoal is the main obstacle-avoidance shoal. The article also analyzes the inflow rate and the maximum possible sea-going volume of the Qiantang River estuary under different hydrological conditions. Based on this, the measures to improve the waterway conditions are proposed.
