摘要
大理至瑞利(大瑞)铁路沿线存在大量的顺层岩质边坡需要支护。以大瑞铁路沿线顺层边坡组合式支挡结构(锚杆框架梁+重力式挡墙)为研究对象,以压缩汶川波作为输入地震波,对顺层边坡支挡结构动力响应进行振动台试验及数值分析,研究顺层边坡在压缩汶川波激振下支挡结构加速度响应,对比分析数值分析结果与振动台试验结果。研究表明:数值分析结果与振动台试验结果的变化规律基本一致,证明振动台模型试验结果的合理性,也证明数值分析方法的可靠性。
Based on support structure project of the railway from Dali to Ruili,dynamic characteristics of retaining structures against bedding slopes are studied by numerical analysis and shaking table experi-ment.It mainly contains acceleration response on retaining structure under Wen-chuan earthquake XZ-excitation.Both of the numerical simulation and the shaking table experiment prove that the results are generally similar to each other.It is found that horizontal /vertical acceleration amplification factor is de-creased with the increase of input field vibrations.The shaking table model test conforms well to the nu-merical simulations,validating that the results of shaking table model test are reasonable and the numeri-cal simulation method is reliable.
