钱塘江塘工技术近期进展

Recent Progress of Seawall Engineering Technology of Qiantang River

该文介绍了钱塘江海塘工程技术的发展情况。钱塘江海塘始于汉代。由于钱塘江水动力强,江道多变,筑塘历尽艰难。通过千余年来的实践摸索,塘工技术不断发展提高,尤其是近期来治江围涂及标准塘建设,引入了新结构、新材料、新工艺,形成了现有的比较科学的海塘断面型式,塘脚防冲结构,以及低滩水中筑塘、软土地基处理、防渗堵漏等新颖施工方法。这些塘工技术对当前治江海塘建设具有较好参考价值。

The article introduces the development of the seawall engineering technology of Qiantang River.The seawall of Qiantang River was built in Han Dynasty. Owing to the powerful hydrodynamics of Qiantang Rive and the varied watercourse, the building of the seawall was extremely hard. Through thousands of years of exploration and practice, the seawall engineering technologies have been continuously developed and improved. Especially in recent years, the new structures, new materials and new technologies are introduced into the process of the river regulation and reclamation and the construction of standard seawall so as to form the existing more scientific sectional type of seawall, the scour resistant structure of seawall toe, and the new construction methods of seawall construction in low beach water, treatment of soft soil foundation, leakage resistance and so on. These new construction technologies are better valuing reference for the current regulation of river and construction of seawall.
