摘　　要：砾石土心墙坝为当地材料坝,最大限度利用当地天然材料是其一大特点。采用砾石土作为防渗料已成为世界高坝发展的趋势,其优点已被国内外工程实践经验所证实。以云南某高砾石土心墙风化料坝砾石土料场的勘察为例,对该工程勘察工作中勘察方案的确定、取样方法、物理力学参数建议及质量评价等方面的方法、经验进行了归纳总结。Gravel earth core wall dam is a local material dam,one of its major characteristics is to maximize the use of local natural materials.Using gravel soil as impervious material has become the trend of the development of high dams in the world,and its advantages have been confirmed by the engineering practice at home and abroad.In this paper,the author is responsible for the investigation of a high gravel soil core wall weathered material dam gravel soil yard in Yunnan Province as an example,and summarizes the methods and experience in the determination of the investigation plan,sampling methods,physical and mechanical parameters and quality evaluation in the investigation work of the project,which has certain reference significance for similar projects.
