According to the demand of topographic form ,I choose diversion hydropower station . The geology condition is good .The main construction conclude the water retaining structure (the concrete non –overfall dam) ,the release works (the concrete over –fall dam) ,the diversion structure (pressure seepage tunnel ,the surgechamber ) ,and the surface power station . The normal water level of the reservoir design water level is 238 m ,its corresponding flow amount is 4800 m3/s .The check level is 240 m ,its corresponding flow is 8500 m3/s .Total reservoir capacity of storage capacity 470000000 performance adjustment is inplete for many power plant is a diversion type power station, a mixed development, development task for power generation, taking into account the ecological water downstream first is the river dam, the layout of water diversion and power generation system。 power plant for diversion type ground workshop, a total installed capacity of 170000 kW, installed capacity of 4 units, the maximum flow rate is 4 = 2 This design to determine the dam site is located in the Piedmont near the top elevation of m, non overflow dam. Bottom elevation 111m. The maximum dam height of . The upstream slope gradient of 1:, the downstream dam slope 1:, dam crest elevation . Key words:Water conservancy。Water retaining structure。Spillway。Diversion type hydropower station。Hoist. 3 前 言 本次畢業(yè)設(shè)計(jì)時(shí)根據(jù)教學(xué)要求， 對(duì)水利水電工程專業(yè)本科畢業(yè)生進(jìn)行的最后一項(xiàng)教學(xué)環(huán)節(jié)。此次畢業(yè)設(shè)計(jì)的內(nèi)容是對(duì)梧桐口水電站首部攔河重力壩的設(shè)計(jì)。它包括了擋水建筑物的設(shè)計(jì)，泄水建筑物的設(shè)計(jì)，工作橋的設(shè)計(jì)。 烏溪江屬衢江
