摘　　要：通过分析当前干滩长度在线测量坡度推算法存在的问题,提出了固定剖面推算法,假定干滩坡面总是以一近乎固定曲面抬升,通过人工实测拟合出初始干滩面曲线,建立干滩面的库长-坝高坐标系,再结合坝顶外坡函数与库水位函数计算出尾矿库干滩长度与滩顶高程,并提出了实现流程软件。该方法较传统坡度推算法精度高、费用低,大大完善了干滩长度在线测量方法。The fixed section calculating method is proposed by analyzing the problems of slope calculation online measurement method of dry beach length. The method suppose the beach upraise in a fixed section,the initial dry beach face curve is fitted out by manually measured method and the coordinate system of pound length to dam height is set up. Combing with the equations of the dam external slope and water line,the software implementation process is proposed. The application results show that,the online measuring method of dry beach is optimized du to the advantages of high-accuracy and low coast of the method.
