| 摘 要： | 应用ANSYS有限元软件,建立U形预应力整体式闸室结构的三维模型,对整体式闸室结构在不同工况下的应力、变形情况进行模拟计算,计算结果表明将U形预应力工艺应用于整体式闸室结构中是可行的,可以较好地解决采用普通钢筋混凝土设计整体式闸室结构时存在的截面尺寸大、配筋量大及裂缝开展宽度不易满足的问题,从而为设计整体式闸室结构提供参考.

| Abstract: | Based on the finite element software ANSYS, this paper builds up a 3D finite element model of monolithic lock chamber structure to conduct a simulation for the stress and deformation of this chamber structure in different conditions. The result shows that U-shape reinforcement prestressing technology used in depressed chamber structure is feasible, which not only provides solution to the problem of concrete crack, but also cuts down the cost of reinforcing bar. Thus it may serve as reference for the design of monolithic lock chamber. |
