成勘院在胜利完成“七五”国家重点科技攻关四项专题研究任务以后,积极组织力量编写出了“八五”国家科技攻关三项课题和三项专题的可行性研究报告,并向能源部申报。于1991年10月完成了与能源部签订“八五”国家重点科技攻关三项专题合同,攻关目标为:1.“高强度大体积混凝土材料特性研究”,攻关目标是结合二滩拱坝施工设计,开展了对大体积混凝土的力学、变形、热学、渗透、耐久性以及破坏机理等关键技术研究。达到提高大体积混凝土使用强度;增强混凝土抗裂、抗冲、耐磨能力;改善混凝土的物理性能;优化配合比设计;从而达到经济可靠的目的,并使我国坝工建设的技术水平更进一步提高。
After successfully completing the four special research tasks of the state’s key scientific and technological breakthroughs in the “Seventh Five-Year Plan” period, Chengben Research Institute actively organized and prepared the feasibility study report on the three topics of the national scientific and technological research in the “Eighth Five-Year Plan” and the three special topics, Ministry to declare. In October 1991, the company completed the three special contracts with the Ministry of Energy for “National 8th Five-Year Plan” national key scientific and technological project. The objectives of the research are as follows: 1. “The research on the characteristics of high strength and mass concrete materials”, the key objective is to combine Ertan arch dam construction Design, carried out on the mass concrete mechanics, deformation, heat, penetration, durability and destruction of key technologies such as research. So as to increase the intensity of use of mass concrete; enhance the ability of cracking, impacting and abrasion resistance of concrete; improve the physical performance of concrete; optimize the design of mixture ratio so as to achieve economic and reliable purposes and further improve the technical level of dam construction in China .
