摘要
运用二维水流数值模拟方法,计算比较了在宜昌～枝城的长江河段内选取重点控制河段,进行护底加糙及回填深槽对维护并抬高宜昌水位的效果.计算结果表明,两种整治措施均能满足要求.
Effects roughness addition are calculated and regulation measure of maintenance and raise of water level at Yichang Station by river bottom protection and method and pool back-fill method in the reach from Yichang to Zhicheng of the Changjiang River compared by using a 2-D flow numerical simulation method. Calculation results show that each can meet demands.
