摘　　要：由于坝体中某测点最大沉降量与全坝体(高)的沉降量在概念上和数值上完全不同,故将坝体测点最大沉降量视作坝体总沉降量,并以此值与坝高相比作为评价面板堆石坝坝体填筑辗压质量,显然是片面的。采用分层叠加求和法计算大坝沉降量,避免了由于测点安装高程及安装层数的不同导致测值的随机性和人为性,通过求出的坝体沉降量及相对沉降率作为评价依据更具有科学性。As the maximum settlement of one measuring point in dam is completely different from the total settlement of dam in terms of concept and value, it is partial to consider the former as the latter and further compare the value with dam height to evaluate the filling and rolling quality of face Rockfill dam. This study used layered stack summation to calculate the dam settlement, avoiding the randoumess and man - induced factors due to differences in height of measuring point and number of layers. The calculated dam settlement and relative settlement rate is more scientific as evaluation basis.
