摘要
钢板桩围堰以其刚度大、效率高、施工简便等优点在水利工程中广泛采用,但其传统的结构计算方法比较复杂,随着有限元技术在渗流计算方面的不断发展,有限元计算钢板桩围堰日渐成熟。本文结合实际工程利用数值计算,分析钢板桩在不同的打入位置和入土深度下渗流场的变化,分析其对围堰边坡稳定性的影响,计算结果与实际相符合,为工程建设施工提供参考。
For sheet-pile cofferdam has the advantages of large structural stiffness, high efficiency, easy operation and so on, it is applied broadly in hydraulic engineerings, but its traditional calculating methods are complex. With the development of finite element technique in the calculation of seepage flow, using FEM to calculate the sheet-pile cofferdam becomes mature with each passing day. Here combined with practical engineerings and by using the numerical calculation, the seepage field changes caused by driving the piles into different locations and depths are analyzed, then the impacts of the piles on the slope stability of the cofferdam are also analyzed. The calculation result is presented to agree with the fact and could provide important bases for project construction.
