摘要
以国道318线黄草坪2^#隧道进洞口为原型开展大型振动台物理模型试验研究。介绍试验模型相似关系、模型材料、模型箱体设计、测试方案和加载制度，对隧道洞口段衬砌结构、洞门建筑以及洞口仰坡的加速度、动土压力、动态位移及动态应变反应规律进行系统分析，对黄草坪2^#隧道洞口段的地震安全性进行评价。
The entry portal of NO. 2 Huangcao Ping Tunnel located on State Highway of NO. 318 is selected as the prototype to make large shaking table test. Firstly, the similarity relation, the moulding material, the mouldcase design, the test scheme and the load subsequence is introduced, and then the dynamic response of acceleration, earth pressure, displacement and strain occurred on the portal lining, the portal structure and the portal slope is systematically analyzed, and finally give the evaluation on seismic safety of the NO. 2 Huangcao Ping Tunnel.
