摘要
为了进行下穿高铁城市矩形隧道减震层材料优选研究,以某城市浅埋矩形隧道工程为例,利用数值软件ABAQUS对海绵橡胶板和硬质聚氨酯板2种材料的减震效果进行分析。研究结果表明:施设10 cm厚海绵橡胶板时,安全系数减震效果最大为249.20%,施设10 cm厚硬质聚氨酯板时,安全系数减震效果最大为200.31%。施设10 cm厚海绵橡胶板减震效果优于10 cm厚硬质聚氨酯板。
In order to carry out the research on the optimization of the shock-absorbing layer material of the rectangular tunnel under the high-speed railway,this paper uses the numerical software ABAQUS to analyze the shock absorption effect of the two materials of sponge rubber sheet and rigid polyurethane sheet based on the shallow buried rectangular tunnel project in a city.The results of the study indicate that when the 10cm thick sponge rubber sheet is installed,the maximum safety factor damping effect is 249.20%.When a 10cm thick rigid polyurethane board is installed,the maximum safety factor damping effect is 200.31%.The damping effect of the 10cm thick sponge rubber sheet is better than the 10cm thick rigid polyurethane sheet.
