长江滨江城市环境保护工程之一——汉口边滩防洪及环境综合治理效益浅析

Flood Disaster Control of Riparian Bars in Hankou in the Yangtze River and Research of Environment Protection

从定、动床试验及环境保护进行分析研究。定床试验 :研究工程实施后 ,本河段的水位 ,流速、流态及天兴洲左右汊分流比的变化 ;动床试验 :研究在不同典型水文年条件下的河势、河道冲淤变化及疏浚区的回淤问题 ,为治理方案的比选优化及工程决策提供科学依据。这是长江干流滨江城市河道整治的先声 ,是城市规划建设中环境保护工程实施的首例 ,意义重大。其环境。
