摘　　要：临涣煤矿是淮北矿业集团的主要大型煤矿,于1985年投产,设计年产煤180万吨。该矿主井提升系统塔高64.5m(8层),外剪力墙内框架矩形钢筋混凝土结构。本文采用SAP2000有限元软件,通过选用不同的阻尼器以及支撑布置方式,比较了结构安装黏滞阻尼器后与原结构在地震作用下的动力响应,以及不同的布置方式下阻尼器的耗能减震效果,可为结构在未来的抗震加固中提供一种优选方案和参考。Linhuan coal mine is one of the main coal mines in Huaibei Mining Group. It began to operate in 1985. The annual designed capacity is 1.8 million tons. The height of the main well tower in this mine is 64.5 meters （8 floors）. This building is frame-shear wall structure. A 3D model of the building is set up with the finite element analysis software SAP2000 in this paper. Different dampers and layouts of braces are added to the model. The best scheme of damper and layout pattern is found out for the future seismic strengthening by comparing the seismic responses of the model with different dampers and layouts of braces.
