摘要
为实现泄冲闸、进水闸和土坝结合部位三维渗流场真实区域的数值模拟,采用有限体积法对含排水孔在内的闸坝区三维渗流场进行了网格划分。根据计算结果可知,闸基处防渗墙效果微弱,溢出点垂直坡降大于允许值,对工程不利,并提出了相应的改进措施。
In order to realize the calculation of the three-dimensional seepage field including the gate and earth dam, grids of the seepage field with the drain hole are set up by use of finite volume method; and consequently sluice seepage field is numerically simulated. According to numerical result, the effect of impervious wall in sluice foundation is weak; and the upright hydraulic slope of overflow point beyond the permission value. The corresponding reform measure is put forward.
