Research On Temperature Control And Smulation Analysis Of Mass Conrete Construction

Along with the flourish development of our country hydroelectricity cause flourish develops and the need of West Development, the hydroelectricity project develops towards big-storage capacity,big-pack machine,large-scale direction, the hydroelectricity-mass concreting warehouse has marched toward 1000m~2 level square metre from several hundreds of previously face to face 2000 m~2 level flight of steps, concrete piece thickness even amounting to more than 10 meters. Adds on various local general climate burning hot temperature toplummet frequently, warm controls guards against the crack measure tobe extremely arduous. Because the hydraulic engineering structurecrack mostly belongs to the temperature crack, therefore, the thisarticle main content is: Conducts the research to the mass concreteconstruction temperature control measure, and using cornputersimulation analogue result analysis, thus to warm controlled themeasure to provide the important proof and the reference.This article based on the heat transfer theory, utilizationlarge-scale finite element software, has carried on the simulation tothe temperature control process, provides the essential theory basisfor the project use, and the obtained result and the actual resultcontrast analysis, has the important project application value and thepractical significance.Main the main body of a book content as follows:1. Have sketched cause and influencing factor that the current situation and temperature rift that big volume concrete temperatures under the control of study produce.2. The analytical principle introducing finite element method and the same the temperature in the project simulating analysis process , being that the hereafter is similar charge problem for providing a reference.3. Introduce big volume concrete temperature under the control of standard and technology measure.4. Union project example, in view of project in actual situation and soon material performance, construction plan and temperature controlmeasure, has actual carried on various models minute stationing placetemperature actual. At the same time, carries on the temperature fieldand the stress field simulation analysis using the finite element,carries on the contrast analysis to the analogue result and the actualresult, thus to simulated the process and the actual situation hascarried on the mutual confirmation.Its research for similar roughly accumulated the water conservancyproject concrete project warm to control guards against the crack toprovide significant the reference...
