文中根据刚体动力学及动量守恒定理，建立起颗粒–壁面碰撞三维数学模型，并采用此三维数学模型研究了壁面约束效应对细长颗粒流化特性的影响。
The three-dimensional particle-wall collision mathematical models were founded in the light of the kinetic of rigid and the momentum conservation law, and the effects of wall on the f.
并对比两种情况下的动测曲线，发现桩顶受约束时桩的动测曲线不仅受桩周土体的影响，还受到上部结构的干扰，并且桩身反射的三维效应更明显。
The dynamic tests of top-restricted concrete pile are affected not only by the soil around pile, but also by the upper structure, and the signal of 3D effect reflected by the pile is stronger.
结合科恩布赖茵拱坝的工程实例，就基础对拱坝坝体的约束效应进行了三维有限元分析，发现施工时预留的陡坎对拱坝坝体应力影响显著，同时建议拱坝施工时地基开挖成概化的地基界面。
