Abstract
Asphalt concrete core wall dam is a kind of dam type design of water conservancy project,and its core part is to use asphalt concrete as the core wall.In order to improve the seismic safety of asphalt concrete core wall dam,the Lannishan Reservoir Project in Bijiang District,Tongren City,Guizhou Province was taken as the research object,and the random response analysis was carried out in combination with the spatial variability of dam materials and random ground motion.The experimental results show that the horizontal peak acceleration of the dam crest is larger,which is 4.48 m/s2 and 5.68 m/s2 respectively,considering the spatial variability of materials and random ground motion.It can be seen that the research method has certain reference value for the seismic safety analysis of Lannishan asphalt concrete core wall dam.关键词
