庆云大淀拦河闸施工排水措施

在深基坑、高水位、土基础水利工程施工中,施工排水是很重要的一环,它的成败直接关系工程建设能否正常进行,也是关系到工程质量、工程进度和工程效益的大事,因此,在施工前根据不同的工程情况,选择行之有效的方案至关重要.山东省水利工程局承建的庆云大淀拦河闸工程在施工排水方面采取了以下措施.

The scheme optimization on construction diversion with discharge control feature of upstream operational reservoir

There is a discharge control feature of construction diversion system with the upstream operational reservoir. The risk evaluation model of construction diversion is established by taking into consideration the risk factors of construction diversion system with discharge control feature as well as their composition. And the risk factors include the upstream operational reservoir discharge control, the interval flood and branch flood and the diversion system itself. And then based on analyzing of the conversion relation between risk index and investment index of diversion scheme, the risk control and conversion principals of diversion system are put forward, and the feasible diversion scheme model is built. At last, the risk and economic evaluation and scheme economic feasibility analysis method of diversion scheme are shown by an example of construction diversion scheme optimization with the discharge control condition of upstream hydropower station. The study is valuable for establishment and optimization of construction diversion scheme with upstream reservoir discharge control.
