庫容又是水庫調度不可忽視的問題,而庫容又與水庫的橫、縱斷面、水位、水深有關,由於泥沙淤積、降水量多少等原因,水庫水量是動態的,不對水庫水量正確調度,會在大洪水時,造成水庫堤壩漫溢甚至垮壩。The result show that the position of free surface is higher because of frusta of brake, especial obvious in the head of frusta of brake ; flux coefficient and pressure on dam are quite influenced by type of frusta and 3 a type frusta of brake relative to 2 type frusta of brake has bigger flux coefficient and smaller pressure on dam ; obvious influence of ability of discharge flow for different ratio of thickness of frusta and breadth of brake and pressure on dam reduces with increasing ration of thickness of frusta and breadth of brake, while bigger flux coefficient is obtained when tlb = 0. 2
結果表明,閘墩河海大學博士論文的存在抬高了水面線的位置,其中在閘墩頭部尤其明顯;墩型對流量系數和壩面壓力影響較大, 3a型閘墩相對於2型閘墩具有更大的流量系數和更小的壩面壓力:不同的墩厚閘寬比t / b對泄流能力也將產生顯著的影響,隨著墩厚閘寬比的增加,壩面壓力降低,而當t / b二0 . 2時溢流壩具有更大的流量系數。There are many main buildings in the plant such as concrete - faced rockfill darn, the second darn with clay core, spillway, diversion tunnel, surge tank, ground workshop and switch mom etc
電站的主要建築物有砼面板堆石壩、粘土心墻二壩、溢洪道、引水隧洞、調壓井、地面廠房和開關站等。In the light of the study result that the energy dissipation ratio is higher as the spillway slope is gentle, to applied stepped spillway to overflow earth - rock dams with a certain height is proposed
根據壩坡較緩時,階梯的消能率較高的研究成果,提出把階梯溢流應用於一定高度過水土石壩。Additionally, the government constructed 3 subsidiary dams, situated at rocky harbour and the sai kung peninsula. the purpose of this was to close up shallow valleys in order to prevent water overflowing through this naturally depressed terrain
除東、西主壩外,另於糧船灣洲、西貢半島建有三條規模較小的副壩,功用在封閉相鄰的山谷,並防止水庫滿溢。( 6 ) 3d integer model of spillway and frusta of brake are established and numerical computation of 3d viscous flow over spillway is completed. the influence of frusta of brake for design parameters such as shape of free surface, pressure on dam, flux coefficient is computed aim at type of frusta of brake and disposal on dam and compute result of different type of frusta and disposal model is compared
6 )通過建立溢流壩和閘墩的三維整體模型,完成了對三維過壩水流粘流場的數值計算,針對閘墩的型式及在壩面的布置計算了閘墩對水面線形狀、壩面壓力、流量系數等設計參數的影響,並將不同墩型與布置形式的計算結果進行比較。The main reason of the stepped spillway having greater energy dissipation is tha there is big horizontal vortex in the inner angel of the steps and it makes momenbo exchange with outer mainstream then accelerates the theulence in the water
由於階梯的存在,使得水流在階梯凹角內產生強烈的水平橫軸旋渦,旋滾水流與外部主流之間不斷進行的動量交換加劇了水流內部的紊動,從而使階梯溢流壩有較高的消能率。Controlled quarry blasting for dam - filling materials in spillway at gongbo gorge hydropower station
