deep overburden

基本解释

The deep overburden will also appear horizontal displacement to upper and down streams after dam construction.
受坝体的影响，坝基深厚覆盖层也会向上、下游发生水平位移；
Through calculation and synthetical analysis, the paper draws conclusions about earthquake response of rockfill dams on deep overburden.
通过实例计算和分析，表明覆盖层的分布对其上堆石坝的地震响应影响较大。
For Asphalt Concrete Core-wall Dams built on deep overburden layers, the status of stress and deformation of dam body and Core-wall are both complex;
对于深厚覆盖层上的沥青混凝土心墙堆石坝，坝体与沥青混凝土心墙的应力变形较为复杂，坝基混凝土防渗墙在施工期和蓄水期的应力应变也较为复杂。
