Method for arranging preposed retaining wall at water inlet of hydropower station
The invention provides a method for arranging a preposed retaining wall at a water inlet of a hydropower station, which comprises the following steps of: aiming at the water inlet of the hydropower station, calculating to obtain the minimum distance between the preposed retaining wall and a water inlet tower and the highest limit value of the elevation of the top of the preposed retaining wall by limiting the horizontal flow velocity of a water body passing through the top of the preposed retaining wall and the vertical flow velocity of the water body passing through the top in the preposed retaining wall; and finally, the distance between the front retaining wall and the water inlet tower and the top elevation of the front retaining wall are verified and selected through water temperature influence analysis of the water inlet of the hydropower station and numerical analysis of the flow state of the water inlet. The systematic and reliable method is provided for arrangement of the front retaining wall of the water inlet of the hydropower station, by means of calculation, verification and value selection of the distance between the front retaining wall and the water inlet tower and the elevation of the top of the front retaining wall, slope excavation of a mountain on the rear side of the water inlet tower can be conveniently controlled, project investment is optimized, meanwhile, the temperature of discharged water is greatly increased, and the service life of the water inlet tower is prolonged. The ecological environment problem caused by the change of the water temperature of the discharged water body is relieved, and the method can be vigorously popularized and applied in practical engineering.
本发明提供一种水电站进水口前置挡墙的设置方法，针对水电站进水口，通过对水体过前置挡墙顶部的水平向流速和过前置挡墙内顶部竖向流速的限制，计算得到前置挡墙与进水塔间距的最小距离和前置挡墙顶部高程设置的最高限值，最后通过对水电站进水口的水温影响分析和进水口流态的数值分析，对前置挡墙与进水塔间距和前置挡墙顶部高程进行验证和选值。本发明为水电站进水口的前置挡墙设置提供了系统可靠的方法，通过前置挡墙与进水塔间距和前置挡墙顶部高程的计算、验证和选值，以便于对进水塔后侧山体的边坡开挖进行控制，优化工程投资，同时使得下泄水温有较大提升，缓解了下泄水体水温变化所引发的生态环境问题，在实际工程中可大力推广应用。
