摘　　要：在某干旱地区,拟建蓄水池为城区供水。当地黏性土资源较为匮乏,但风积、冲湖积砂储量丰富。针对该问题,本着节约资源和降低成本的目的,通过室内物理力学试验、击实试验、现场原位测试、工程类比等方法,对细砂作为填筑坝体材料的可能性进行了研究分析,并评价其适用性。为水利工程利用细砂筑坝提供可靠性依据,亦为其它类似工程实践提供了借鉴作用。In an arid region,a reservoir is proposed to supply water to urban areas.Given the distant location of alternative borrow area and the scarcity of local cohesive soil resources,this study evaluates the feasibility of using fine sand as dam construction material.To address these challenges while prioritizing resource conservation and cost reduction,a series of investigations are conducted,including laboratory physical and mechanical tests,compaction tests,field in-situ testing,and engineering analogies.The findings provide a reliable basis for the application of fine sand in hydraulic engineering and offer practical insights for similar projects.
