盾构隧道半径及埋深对其地震响应的影响分析
|
摘要
针对目前出现的大半径盾构隧道,通过建立土—隧道的数值计算模型,分析了隧道半径及埋深对其地震响应的影响,研究表明:随着隧道半径的增大,隧道拱顶的竖向位移及弯矩均显著增加,且增加隧道埋深有助于提高其抗震能力。
According to the large-radius shield tunnel at present,it analyses the influence of tunnel radius and depth to its seismic response through setting up the numerical calculation model of soil-tunnel.The research shows that with the increasing of tunnel radius,the vertical moving of tunnel arch top and moment is increased remarkably and increasing tunnel depth is good to improve its seismic property.
