The Stability Analysis Of The Letting Out Trough Biteplate Of Top Spillway Of Local Material Dam

In the project structural design, the ideal design plan with feasible and economy has been the purpose that the project designer has sought assiduously all the time. To build the reservoir in the alpine gorge area, because generally there are abundant building sand stones in this area, flow relatively light and downstream water level low characteristic, soil stone dam is a comparatively ideal scheme. But under situation of precipitous in the lie of the mountain of two sides, the rich massif and no suitable Ya's mouth to build the spillway ,building bank spillway ,fabrication cost will very high , so to appear the innovation of spillway. On the top of dam. The normal or extraordinary spillway is assigned on the top of dam directly, which can simplify pivot assignment, save project fabrication cost and convenient advantage of constructing etc., this subject is paid attention to by project circle. At present the spillway on the top of panel rock-fill dam is successful, but domestic and international the project about spillway on the top of dam is actually few, and it is less to its structural design theoretical research, only a small amount of experiments . In view of the above situation, this article proceeds from the aspect of states and use the theory mechanics , mechanics of materials , soil mechanics , hydraulics , structural mechanics , elastic mechanics and the analysis of structural reliability and so on to analyze the letting out the trough biteplate of the different patterns of the spillway on the top of local material dam, to calculate internal force and structural reliability ,and have set up the resistant slipped and resistant toppled steady mechanics model. and the relational expression between dam downstream slope corner and all strength acting on biteplate and between level hinder slide plate length and every strength of received it to be derived and the safety coefficient relational expression, and have offered the theory computing method for engineering design in the future. In addition, for realizing to calculate internal force in biteplate and structural reliability and facilitating calculation in engineering design in the future, this article utilize LabVIEW language innovative software of U.S.A. NI Company to compile the computer program of Guo check form method calculating elastic ground roof beam internal force of automatically check form and draw pictures and the generality strong computer program of JC calculating structural reliability; and their reliability are proved by the instance...
