摘　　要：由于挡土、挡水的需要,围堰成为必不可少的工程元素之一,而钢板桩围堰凭借其施工简便、挡水性好、可重复使用等优点,在工程中的应用越来越广泛。钢板桩围堰在支护计算方面主要采用等值梁法和平面有限元法,简化的方法与实际的工况有一定的偏差,因此本文采用三维有限元软件Midas对钢板桩围堰建立空间结构模型,模拟围堰真实的受力状态。With the increasing of engineering construction,cofferdam has become one of the indispensable engineering,due to the need to retain earth and water.And steel sheet pile cofferdam is widely applied in engineering with its advantages of simple construction,good water retaining and reusability.The main method used in supporting computing of steel sheet pile cofferdam is＂equivalent beam method＂and＂plane finite element method＂,but the simplified method has a certain deviation with the actual conditions.And therefore,this article established a spatial structure model of steel sheet pile cofferdam with Midas threedimensional finite element software,to simulate the real stress state of cofferdam.
