筒形导管架桩基防波堤结构及其经济分析

Structural Design and Economic Analysis of Breakwater with Cylindrical Jacket and Pile Foundations

随着我国航运事业的迅速发展,新建防波堤工程面临的水文条件和地质条件愈加恶劣。本文针对天津港地区典型的水文和地质条件,依据现有防波堤结构相关设计规范,研究提出了防波堤结构尺寸,并根据2019年沿海港口水工建筑工程定额提出了筒形导管架桩基结构的直接定额费,并对其经济性进行分析。应用结果表明,本文设计的筒形导管架桩基防波堤结构工程费用合理。

With the rapid development of shipping industry in China,the hydrological and geological conditions of the new breakwater project are becoming worse.In view of deep water and soft soil foundation,based on the design concept of cylindrical foundation structure,pile foundation structure and jacket,this paper puts forward a new type of breakwater with cylindrical jacket and pile foundations,and introduces the main design parameters.In view of the typical hydrological and geological conditions in Tianjin Port,the sizes of the new structure are determined according to the relevant design specifications.According to the 2019 coastal port hydraulic construction project quota,the direct quota fee of a group of structure with cylindrical jacket and pile foundations is determined,and its economy is analyzed.The results show that the cost of this breakwater is reasonable.
