摘要
对于高地震烈度区的输水隧洞建设而言,采取有效的减震工程措施是极为必要的。文章以新疆库尉地区输水工程输水隧洞为例,利用有限元数值模拟方法对减震层的材料和厚度进行优化研究,结果表明库尉输水隧洞施工建设中应采用厚度为40cm的注浆减震层,获得最佳减震效果。
For the construction of water conveyance tunnels in high seismic intensity areas,it is extremely necessary to take effective measures to reduce earthquake.Taking the water conveyance tunnel in Kuwei area of Xinjiang as an example,the material and thickness of the shock absorber layer are optimized by finite element numerical simulation.lt is suggested that the 40 cm thick grouting shock absorber layer be used in the construction of the water conveyance tunnel in order to obtain the best shock absorber effect.
