中文摘要：
某拟建坝基覆盖层深，层厚变化大，物质多样，物质分布不均，坝基沉降量大，不均匀沉降显著。采用分层总和法和三维数值模拟，对心墙坝和面板坝两种坝型的坝基沉降变形进行分析评价。发现两种坝型的坝基覆盖层沉降变形和不均匀沉降均未超过规范量值，但面板坝沉降量和沉降差皆优于心墙坝。
英文摘要：
A to-be-built dam is characterized by deep covering, big thickness variation, diverse matters, uneven distribution of matters, notable foundation settlement, and marked uneven settlement. Layer-wise summation method and three dimensional numerical simulation method are used to evaluate the deformation and settlement with two kinds of dams, core-wall dam and face dam. The deformation and uneven settlement in neither case exceed the standard value, but the face dam is superior to the core-wall dam in both settlement and differential settlement.
