摘要
在总结国内外土石坝建设关键技术问题研究成果的基础上,针对中国西部高土石坝建设特点,着重讨论高应力条件下土石料的试验方法、强度变形特性与本构模型、长期变形特性、动力特性与本构关系以及土与结构接触面力学特性等关键技术问题,并探讨了进一步研究的方向和主要科学问题.
The existing results in the construction of worldwide earth-rockfill dams were summarized. With regard to the construction of high earth-rockfill dams of hydropower development in West China,many key technical problems of earth-rock materials were emphatically discussed,including the test methods under high stress conditions,the strength deformation properties and constitutive models,the long-term deformation properties,the dynamic properties and constitutive relations as well as the mechanical properties of contact faces between soils and structures. On such a basis,the research interests and the main scientific problems in the future were discussed based on the above analyses.
