摘　　要：以新疆某碾压式沥青混凝土心墙为例,探讨以砂砾石为筑坝材料土石坝的沉降变形计算方法,分别应用公式法、二维有限元法和三维有限元法分析土石坝的沉降变形特点,结合已建工程实例,验证计算的可靠性,以期为类似工程提供借鉴。Taking a rolling asphalt concrete core wall in Xinjiang as an example,this paper mainly discusses the settlement and deformation calculation method of earth rock dam with sand gravel as the dam material,and analyzes the settlement and deformation characteristics of earth rock dam with formula method,two-dimensional and three-dimensional finite element method respectively,and verifies the reliability of the calculation model combined with the built project examples,so as to provide reference for similar projects.
