The Research Of Safe Operation And Optimization Control About Hydraulic Engineering

Water is the source of life, it not only related to people’s basic production and living,but also is the foundation of social and economic development what can not be replaced.Hydraulic engineering is the important infrastructure of national economy, only under thecondition of safe operation can effective play to flood prevention and waterlogging control,irrigation and drought, production and living water supply. In recent years, China’sinvestment in hydraulic engineering is more and more big, the construction of hydraulicengineering is more and more attention. Meanwhile, the problem about safe operation ofhydraulic engineering related to people’s lives and property security and social stability ismore and more attention. Safe operation of hydraulic engineering is a necessaryprecondition for water conservancy engineering construction, the safety control is mainlymanifested in two stages of engineering design and operation management. Therefore, thispaper will make a study on safety management and optimization control of hydraulicengineering from the stage of design and operation. At the design stage,will take theoptimal layout of air valves on the long-distance water pipelines as an example, and to findan optimal air valve parameters and their arrangement scheme through the correspondingcalculation; during the operation phase, this will take the piezometric level’s forecast ofearth-rock dam seepage monitoring model as an example, improve the prediction accuracythrough optimization algorithm, and then analyze the monitoring data, to keep abreast ofthe running state and seepage change of the dam, to prevent the earth-rock dam causeserious damage for seepage failure.Therefore the main content of this paper is summarized as follows:(1) Based on the analysis and comparison of several common safety monitoringmodel about earth-rock dam, established the earth-rock dam seepage safety monitoringmodel with support vector machine (SVM).(2) Based on the research of basic principles of the simplex particle swarmoptimization (SMPSO), proposed the earth-rock dam seepage safety monitoring modelbased on simplex particle swarm optimization algorithm optimized correlation parametersof support vector machine,and the algorithm is applied to an instance of earth-rock damseepage monitoring. Through the instance, also analyzed the prediction results aboutconsidering nonlinear term of influencing factors or not in the factors selection of model. (3) Summarized the basic principle of hydraulic transient and the protective measuresof water hammer, thereby established a hydraulic transient calculation model of longdistance artesian water pipe.Based on the comparative analysis of several common airvalves, using compound air valve to control the negative pressure of water hammer. Thispaper also use the orthogonal experimental design method to ensure the safe operation ofwater pipe through the analysis of variance to get the optimal intake/exhaust aperture andlayout schemes of air valves above the water pipe.(4) In the last section of the paper, the whole research is summarized and theprospects to the further research are put forward.
