截流水工模型试验大纲初稿(国外英文资料) 1, the general situation of 1.1 project summary Area of hydropower station is located in the yalong river downstream, liangshan yi autonomous prefecture, sichuan province, luo village in xichang and yanyuan county border, yalong river Carla to river mouth of the river hydropower planning five development way of the third cascade hydropower stations. The upstream is connected with the tail water of the jinping secondary power station, the reservoir area is about 58km long, and the downstream of the hydropower station is about 145km apart from the two tan hydropower station. It is about 80km from west changchang road. The main task of the project is to generate electricity, and the reservoirs normal water level is 1330.00 m. The water level is 1328.00 m, and the total storage capacity is 753 million m3, which is the daily regulating reservoir. The engineering grade is first-class engineering, the main hydraulic building is 1, the secondary building is 3, and the temporary building is 4. Power station hub buildings is mainly composed of full retaining dam, holes in the dam section and computation (roller compacted concrete gravity dam), stilling basin, the right bank diversion system composition, the dam is 168.00 m high, on the right bank underground powerhouse installed 4 units of 600 mw unit, the total installed capacity of 2400 mw. The hydropower station recommends the diversion scheme of the weir weir, the tunnel diversion and the whole year construction of the foundation pit. The early diversion building includes a diversion tunnel and a cofferdam. The two guides are arranged on the left and right bank, with a section size of 16 by 19m (wide by high). On the left bank, the entrance of the entrance is 1200.00 m, the height of the exit is 1200.00 m, the hole is 744.137 m, and the slope is 5.38 ‰. The entrance to the bottom of the inlet is 1199.881 m, and the hole length is 1018.6 m, and the slope 4.04 ‰. DAMS upstream and downstream cofferdam
