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。
Some proposed dam basement cover depth, layer thickness changes, material diversity, uneven material distribution, dam foundation settlement, uneven settlement significantly. The stratified summation method and three-dimensional numerical simulation are used to analyze and evaluate the settlement of two kinds of dam foundation such as core wall dam and panel dam. It is found that neither the deformation nor the uniform settlement of the overburden of dam foundation of the two types of dams has exceeded the normative value, but the settlement and settlement difference of dams are better than that of the core wall dam.
