高烈度地震区隧道洞口段地震安全性分析及评价
|
摘要
目前,有关高烈度地震区山岭隧道地震安全性分析与评价的研究尚不多见。文章以国道318线黄草坪2#隧道为工程原型,在数值模拟计算和振动台物理模型试验结果分析的基础上,分别从洞口边坡、洞门建筑、洞口段衬砌及围岩三个部位对该隧道洞口段进行地震安全性分析,并结合各部位拟设抗、减震措施,对其进行了整体地震安全性评价。结果表明,该隧道洞口段在设计地震作用下是足够安全的。
Of late,rare papers have been published for the analysis and evaluation of the seismic safety of tunnels in regions of high seismic intensity.Taking Huangcaoping No.2 Tunnel on 318 State Highway as the background,seismic safety analysis on the portal section was carried out with respect to slope,building,lining and rock mass by means of numerical simulation analysis and vibration table model test.Meanwhile corresponding aseismic countermeasures were put forward for various parts,and overall seismic safety evaluation was conducted.Results indicated that the portal section will be safe under the designed earthquake.
