The Third Generation Of Nuclear Power Island Raft Foundation Mass Concrete Crack Control And Construction Technology Research

With the development of our economy construction, demand for electricity, gap isbigger and bigger, on the other hand, from the national energy strategy of sustainabledevelopment point of view, as well as the international community pays more and moreattention to greenhouse gas emissions, climate warming situation, actively promote theconstruction of nuclear power construction of energy in China, is an important policy.In the development of nuclear power, nuclear safety become the focus of attention, andnuclear reactor plant raft as reactor "base", is the nuclear safety an important barrier, but tonuclear reactor plant raft foundation mass concrete research is not deep and perfect,especially the lack of the measured data analysis and information feedback and so onnuclear island raft foundation mass concrete research is particularly important. At the sametime, among the third generation of nuclear power plant construction in the countryvigorously, the Taishan nuclear power plant as the first EPR-type nuclear power plant,charged with the important task of promotion and localization of EPR-type nuclear powerplants in our country, and therefore for the study of the EPR-type nuclear power plants raftfoundation mass concrete construction technology has a very important significance.This paper first introduces the current development trend of the third generationnuclear power plant, under this background extraction of raft foundation of nuclear powerplant construction technology of large volume concrete of the necessity and importance ofraft foundation of nuclear power plant, and then points out that the construction of largevolume concrete crack control of main control points is, on this basis, the system analysisof the large volume concrete cracks reasons for nuclear power plant, points out the control of large volume concrete crack should take " giving priority to prevention, active control "method, and innovative project management dynamic control theory is applied to thecontrol of large volume concrete crack, puts forward the " whole process dynamic control"thought, around the crack control of the main line to arrange other key control points,specifically from the concrete production control, construction process control, detectionand control of the three aspects of the operation, the last of the thought and the controlmethod is applied to the EPR for Taishan nuclear power plant construction, made goodtime limit for a project and economic benefits, to prove the advanced ideas andconstruction technology the correctness and rationality, for similar nuclear power plantconstruction and large volume concrete Control, and provides the basis and reference,while for EPR nuclear power plant and the promotion of domestic to lay the foundation.
