Study on the Rules of Sedimentation in Ningxia Shuidonggou Reservoir Chun-guang LI, Cheng YANG School of Civil Engineering , Beifang University for Nationalities.
With the water level reduction and increase of the water intake amount, the mainstream flow straight to east gradually, and makes the recirculation zone on the right side of the outlet is gradually shrinking. 4.2 Analysis of the reservoir sediment and put forward some engineering suggestions Combined with the simulation results, we analyse the siltation situation of Shuidonggou reservoir and put forward several engineering suggestions.
From the above analysis, we put forward the following engineering suggestions: ① If high water level running is chosen, in order to reduce the water erosion on the left bank of reservoir area, choose the water intake amount is 300,000 m3/d. ② If low water level running is chosen, to reduce the number of inlet and tailing dam sedimentation, choose the water intake amount is 600,000 m3/d. ③At present, the water output amount is 100,000-150,000 m3/d, in order to reduce the erosion on the left bank, and reduce siltation near the inlet, at the same time considering the reservoir safety, we suggest that the reservoir operation water level is between 1179m to 1174.4m. 5.

High-temperature Closure Control Technology of Concrete Arch Bridge Using Cable-Stayed Buckle and Cantilever Construction Method Zhongchu Tiana , Wenping Pengb ,Chao Zhouc School of Civil Engineering and architecture, Changsha university of Science and Technology, Changsha, Hunan, 410114, China atianzhongchu@163.com, bpwp320@163.com, c375132673@qq.com Keywords: Reinforced concrete arch bridge, Cable-stayed buckle and cantilever construction method, High-temperature closure, Pre-jacking force, Counterweight.
The high temperature closure control method of Cantilever arch bridges After the hang suspension casting clasp closure and system transformation of reinforced concrete arch bridge, the bridge will be affected by the influence of the secondary internal force caused by factors such as temperature change.There are two kinds of Arch bridge’s closure temperature effect should be considered mainly: one is temperature gradient effect, usually you can select the closure timing of more uniform temperature in order to avoid its impact (generally choose 0:00 in theeven- ing ~ 7:00 before sunrise ); the other is the system temperature effects, in the actual engineering,due to the duration and conditions of the construction site, there is often difference between thetemperature of closure and design reference temperature.
Engineering situation Located at the expressway from Sinan to Jianhe, the Mupeng Bridge is a reinforced concrete arch bridge with a main span of 165m.
Because of the high-temperature closure, this effect of temperature stress of concrete arch was offset by pre-jacking force and counterweight in the closure.Based on least square method,the calculation method had been proposed to determine the pre-jacking force and additional counterweight and the Mupeng bridge as the engineering example was verified.
