Abstract: Settlement is an important indicator for embankment dam, but the settlement at measuring point should not be considered as the total settlement of the whole embankment dam. Based on the settlement at measuring point, by use of the superposition method, the total settlement and the relative sedimentation rate can be calculated, which can be taken as the basis for assessment of dam quality and safety.

摘要： 沉降是土石坝的重要指标，但不能以坝体某测点沉降量作为坝体坝基总沉降量。应根据坝体测点沉降量，采用分层叠加求和法求得总沉降量及相对沉降率，以此作为评价坝体填筑质量和评估大坝安全的依据。
