摘要
本文以龙穴大型造船基地四二七厂船坞式试验场工程为研究对象,对围堰结构进行设计.本工程地质属典型的软土地基,结合工程基础资料,拟定双排钢板桩围堰作为本工程的围堰形式.对板桩围堰进行结构设计,并利用经验公式校核围堰结构的稳定性.为了使结构设计更加精准,应用有限元软件FLAC3D对双排钢板桩结构作数值模拟计算,并对设计的双排钢板桩结构的内力和强度进行分析,符合承载力设计要求.通过本文的研究,将对大跨度软土地基工程双排钢板桩围堰的设计提供借鉴和有益的参考.
This paper took No. 427 dock of LongXue shipbuilding base as a research object, and designed the cofferdam structure. The double sheet-piled cofferdam was used owing to the soft ground. After the design of the cofferdam, this paper had a stability analysis with empirical formula. To make the design more accurately, this paper used FLAC 3D for numerical simulation. At the last of this paper, it analyzed the force and strength of the structure. The results proved that the design meets the requirements of the structure bearing capacity. This paper will be a useful reference to the design of large span double steel sheet-pile cofferdam.
