The Study On Thermal Stress And Temperature Cracks Control Of Roller Compacted Concrete Gravity Dam In Severe Cold Area

This text carry on artificial analysis simulation some Xinjiang plan to build high RCC gravity dam construction course of piece concrete dam through software ANSYS of large-scale finite element mainly in here, including analysis and course temperature stress analysis of construction of course temperature field of construction, consider cement heat of hydration , roll concrete modulus of elasticity , roll concrete creep with temperature person who change main factor at the same time analyze, and totally according to the reality built hierarchically while constructing in simulation , are calculating a kind of simulation of Central Plains, it is totally identical too that the time while calculating is arranged with the construction scheme。Creep in conformity with the force field through unstable temperature field of dam body and unstable temperature of studying in the construction course, probe into cold area high to roll concrete dam in coherent storehouse build, temperature field sympathetic characteristics and distribution laws of force field rise serially, offer theory and data for temperature-controlled measure to consult. At the same time still in simulation is analyzed, explore a good artificial method of construction, can understand at any time in constructing temperature change and stress change of the structure create the condition for engineers and technicians.
