摘　　要：随着土石坝设计及施工技术的发展,土石坝筑坝材料的选择范围也越来越宽,以往不适合用来进行土石坝填筑的软岩材料,随着施工过程的精细化控制,也越来越多地在实际工程中得到了成功应用。在土石坝工程设计及施工中,针对软岩物理力学特性,结合实际工程具体特点,开展了软岩筑坝的关键技术研究,将软岩最大程度的资源化利用,在保证工程建设运行安全的基础上节省了大量的建设资金。从大坝建设角度对软岩堆石料物理力学特性进行了归纳总结,并在此基础上对土石坝建设过程中的软岩利用提出了建议。With the development of the design and construction technology for earth rockfill dam,the selection range of earth rockfill dam materials has become wider.Soft rock materials that were previously unsuitable for earth rockfill dam construction are now being successfully used in practical projects due to the refinement of construction process.In the design and construction of the earth rockfill dam project,in view of the physical and mechanical properties of soft rock,combined with the specific characteristics of actual project,the research on the key technologies of soft rock dam construction has been carried out to maximize the resource utilization of soft rock,resulting in significant cost savings on the basis of ensuring the safety of project construction and operation.In this paper,the physical and mechanical properties of soft rockfill materials are summarized from the perspective of dam construction.On this basis,suggestions for the utilization of soft rock during the construction of earth rockfill dam are put forward.
