水闸闸室结构三维样条边界元分析

3-D Spline Boundary Element Method for Sluice Analysis

用三维样条边界无法分析水闸闸室结构。底板、闸墩和截水墙等为其子结构，交通桥、工作桥和胸墙等处理为内部支撑。地基和边载可以是任意的，只要能给定地表位移面力关系。在各种工况下，不论是设置平板门还是弧形门，是平底板还是反拱底板，即使在稀疏剖分下也能给出高精度的位移场、应力场和地基反力场。

We analyse the sluice chamber by 3-D spline boundary element method. The floor, piers and in-tercepting walls are its substructures. the traffic bridge, operating bridge and altar are treated as inter-nal supports. The foundation and neighbouring loads may be arbitrary, but it needs the known dis-placement field of earth's surface under unit foras. Even with coarse division. we can obtain thefields of displacement. stress and reactions of chamber in any operating modes with fine precision.whether taking the Planar gate scheme or the radial one.the flat floor or the arch inverted one.
