Ation Arch Dam Construction Temperature Control For Dynamic Simulation Platform Design And Implementation

Dagang mountain hydropower station located in ya ’ an city in shimian County, Sichuan province, is the main stream of dadu River hydropower development planning of the 14 th power station.-Dam of the power station development and hub structures mainly consists of mainly consists of water retaining structures, composed of flood discharge and energy dissipation structures, diversion structures, maximum height of 210 meters, the project’s main features are: complex geological conditions and seismic fortification intensity is high, is currently under construction seismic fortification intensity of the highest arch dam in China.Dagangshan hydropower station high 210 m concrete arch dam largest dam, dam concrete of about 3.3 million m3. Dam concrete temperature due to hydration heat rise, concrete when the temperature drops, temperature stress of concrete under constraint conditions will produce, if not properly controlled, easily lead to cracking of concrete. Crack not only affects the appearance of the buildings, but also reduce the durability of concrete, serious will directly affect the safe operation of the engineering and life.By carrying out simulation research on temperature control measures for construction and construction, complete control of field temperature data on temperature control measures for timely feedback analysis, tracking information on temperature and thermal stress of concrete blocks and make temperature control measures for prevention, prevent dangerous cracks in the concrete. Combined temperature stress dagangshan arch dam concrete during construction and operation phases of the security assessment.Simulation research on temperature control measures and construction of traditional, focused mainly on theoretical calculation and study how combining simulation and engineering reality not by their focus on the content. Difficulties arising from the mainly manifested in the following aspects: first, the simulation of boundary conditions cannot be obtained from the site timely and comprehensive, deviation and delay that it was impossible to track and, secondly, main simulation results using PPT published report or document information, lack of timely and comprehensive publishing and sharing, to guide the construction production.Temperature control measures of the project and construction of simulation platform of finite element simulation is to be closely integrated theory and field construction, integrate research and production, realization of computational analysis, field production, implementation, monitoring and dynamic feedback closed-loop temperature control the whole process management, personalized, precise temperature management, guarantee construction quality and operation safety.
