当水库和潜水之间,存在着水力联系时,在水库工程完工后,水库水位提高时,就产生了潜水回水。当水库水位升高达到稳定时,经过一定时间,潜水回水亦达到了极限高度,此上升高度和水库水位升高相适应。在设计水库工程时,必须考虑到潜水回水,在回水后,水库周围是否产生了沼泽地和土壤的盐碱化,或因潜水回水影响了工厂地基的稳定性等等问题。了解了这些情况,进行技术上措施和经济核算。这样首先要对潜水回水进行计算。过去对潜水回水计算方
When there is a hydraulic connection between the reservoir and the dive, a submersible backwater is generated when the reservoir level is increased after completion of the reservoir project. When the water level in the reservoir reaches a steady state, the submersible water return reaches the ultimate height after a certain period of time, which corresponds to the rising of the reservoir water level. In the design of reservoir projects, we must take into account the submersible backwater, after the backwater, the reservoir has caused the marshes and soil salinization, or due to submersible backwater affected the stability of the factory foundation and so on. Understand these circumstances, carry out technical measures and economic accounting. So first of all to calculate the diving backwater. Back to the calculation of the diving backwater
