| 摘 要： | 模型试验是对隧道工程在地震动荷载作用下破坏机理进行研究的重要手段，而围岩相似材料是隧道模型试验的结果是否准确、符合实际的关键之一。隧道抗减震模型试验围岩相似材料研究的主要内容有：相似比的确定、配制适宜的相似材料和模拟结果及其评价等几个问题。试验结果表明，隧道抗减震的重点在洞口段，应根据不同的情况采取相应的抗减震工程措施。

| Abstract: | Model experiment is an important method to study the tunnel＇ s mechanism of fracture under the seismic load, and one of the keys of the tunnel＇ s model experiment is the simulating material of the surrounding rock. The main matters of the research about the simulating material of surrounding rock are to deduce the similarity scale, confect the feasible simulating material, and evaluate the effect. The experiment indicates that the opening segment of the tunnel is the emphases of earthquake fortification, which requires corresponding earthquake-protective measure. |
