Floating Stability Analysis of Steel Boxed Cofferdam of Dongtinghu Long-Span Bridge

Abstract

With the development of highway and railway, the construction technique of bridge is developing at a lighting speed. Because of the need to across the river and channel, which span getting more and more large, the foundation of the bridge piers should be more and more stable. Lead to raising the load capacity of the pier foundation. The technique cofferdam construction is an effective mean to solve large foundation problems in deep water. And comparing the empirical value to the simulating value, the results demonstrate FLUENT is a reliable program to simulate the water resistance. This paper gives a model for complete resistance calculation and stability analysis of floating steel cofferdam which will provide a template for similar analysis of engineering application.
