摘　　要：针对大气折光变化大、不稳定等特点,提出了一种动态求解大气折光综合系数的方法。在满足各段高差往返差不符值不超限的前提下,求出使得监测网中所有三角形的高差闭合差的加权平均值最小的k值,再对整个三角高程网进行平差计算。以某大坝外观三角高程网为例,验证了该方法的可行性。A method of calculating comprehensive coefficient of atmosphere refraction dynamically is proposed to solve the problems of wide range and unstable etc.in atmosphere refraction.On the premise of satisfying the discrepancy and not exceeding of round trip height difference each measured edge,the minimum value of k is calculated which make the weighted mean of closed height difference in all triangles of monitoring network,then adjustment is calculated in entire trigonometric leveling network.Taking the trigonometric leveling of a dam＇s surface for example,the feasible of method is proved.
