摘要
首先介绍了中国目前高土石坝建设现状,然后回顾了循环加荷动三轴测试技术、堆石料动力性质的研究、高土石坝动力反应分析方法和土石坝地震永久变形的研究进展,最后讨论了高土石坝抗震措施和土石坝地震安全评价及防灾对策专家系统的基本思路。
Construction status of high earth-rock dams in China are introduced firstly,and then cyclic triaxial test technology,study on dynamic properties of rockfill materials,research progress of dynamic response analysis method for high earth-rock dams and earthquake-induced permanent deformation of earth-rock dams are reviewed. Aseismic measures for high earth-rock dams,seismic safety evaluation on earth-rock dams and basic idea of an expert system for disaster prevention measures are discussed finally.
