水工混凝土结构抗震研究进展的回顾和展望
|
摘要
全面概述了中国水利水电科学研究院近50年来在水工混凝土结构抗震研究领域的主要创新性思路和成果的进展,包括其抗震安全评价的三个相互配套的方面。在地震动输入方面为:大坝抗震设防水准框架的制定、场址相关地震动参数的合理确定、坝址地震动输入机制的理解。在结构地震响应方面为:结构抗震的动力分析、结构抗震的动力模型试验、现场测振试验和地震监测、水工抗震设计规范的编制和修订。在大坝混凝土动态抗力方面为:大坝混凝土全级配大试件动态抗折试验、对试验结果的理论探讨、大坝混凝土三维动态细观力学分析、CT技术在混凝土动态抗力研究中的应用。阐述了研究群体形成的主要工作理念为:突出工程观点、强调全面综合评价、重视实践检验、发扬团队协作精神。最后,提出了今后研究的展望。
In this paper the major creative ideals and achievements in seismic study on concrete hydraulic structures in IWHR in the recent 50 years are briefly summarized.Three mutually coordinated aspects are included.For seismic input there are: proper for mulation of a framework of design seismic fortification levels,reasonable selection of the site-specific ground motion parameters,and correct understanding of the seismic input mechanism.For seismic responses of structures there are: dynamic seismic analysis of structures,dynamic model test on shaking table, field test and seismic monitoring,drawing and revision of seismic design code for hydraulic structures.For dynamic behaviors of dam concrete there are: dynamic rupture test of fully-graded dam concrete and explanation of the results,3-D meso-mechanics dynamic analysis of fully-graded specimen of dam concrete,application of the computer topography technique for investigating inner fracture pattern of concrete.Also,the working principles of the research group are set forth, i.e.stressing engineering viewpoint,emphasizing overall evaluation,thinking highly of practical verification and promoting a team collaborating spirit.Finally,further works in seismic research are prospected.
