摘要
结合国内某跨海大桥深水基础钢板桩围堰,应用等值梁法基本原理,研究了在三种不同工况下钢板桩围堰的受力情况,分析了钢板桩在不同工况下的剪力与弯矩分布,计算最大弯矩点和支点反力,并对依托工程钢板桩围堰的稳定性、最大弯矩及整体抗浮进行验算,验算结果均小于界限值,验证了钢板桩围堰的安全性。
Combine with the steel sheet pile cofferdam of a deep-water foundation of a sea-crossing bridge in China,using the principle of equivalent beam method,the stress situation of steel sheet pile cofferdam under three different working conditions is studied,the bending moment and shear force distribution of steel sheet pile under various working conditions are analyzed,the maximum bending moment point and fulcrum reaction force are calculated.Simutaneously the stability,maximum bending moment and overall anti-floating of the steel sheet pile cofferdam relying on the project are checked,the checking result is all less than the limit value,which verifies the safety of the steel sheet pile cofferdam.
