遵照《国家中长期科学和技术规划》中水利学科的水工结构工程创新前沿研究的要求,针对高坝与特高坝以及病险大坝的特点,讨论这些水工结构工程的关键问题及其存在的重大科学技术问题。重点针对应力分析、极限承载和非线性等关键科学技术问题,评述相关代表成果和研究进展,探讨了现行分析理论与方法的长处和不足,提出宏观、细观与纳观3层嵌套分析模型,微纳尺度分析法与随机疲劳理论等发展方向,以及水工结构工程科学中的应力分析、极限承载与非线性等健康诊断的综合分析理论与方法。
In accordance with demands of the National Program for Medium- and Long-term Scientific and Technological Development for cutting-edge research on hydro-structure engineering,and in consideration of the characteristics of high dams,super high dams,and dangerous dams,significant scientific and technological problems in hydro-structure engineering are examined. Representative achievements and progress in research on stress, ultimate bearing capacity, and nonlinearity analysis are reviewed, and then the advantages and disadvantages of current theories and methodologies are analyzed. Finally,development directions,including the macro-meso-nano coupling analysis model,micro-nano scale analysis method,stochastic fatigue theory,and the comprehensive analysis theory and method for health diagnosis based on stress,ultimate bearing capacity,and nonlinearity analyses in hydro-structure engineering,are proposed.
