摘　　要：钢板桩围堰对地下或水下工程起着重要的支撑作用,其安全与否直接关系着工程的安全状况和进度.本文主要针对钢板桩围堰内部各构件的强度和稳定性,结合雅鲁藏布江特大桥工程,应用三维有限元软件对此工程中钢板桩围堰进行三维整体建模并进行结构分析.该方法与传统的等值梁法或平面有限元等简化方法相比更为合理,且验证了此方法的正确性和简便性.计算结果也表明了该工程可以按设计安全施工,并可为其它工程中的深基坑的安全施工提供参考.The steel sheet pile cofferdam is a very important supporting role in the underground or underwater engineering.The safety and progress of the project is directly related to the safety of the steel sheet pile cofferdam.This paper mainly aiming at the strength and stability of the members of the steel sheet pile cofferdam,combined with the Yarlung Zangbo River Bridge project,the steel sheet pile cofferdam of 3Dintegral modeling and structural analyses are carried out using 3Dfinite element software.The method is more reasonable than the traditional method of equivalent beam method or plane finite element method;the correctness and simplicity of the method are verified.The calculation results also show that the project can be designed according to the design safety and provide a reference for the safety of deep foundation pit in other projects.
