结果表明，地震动加速度幅值随深度的增加而减小，在浅层的变化速度较快。 - The multi - point effect with input of the artificial earthquake acceleration simulated by interpolation method is weaker than that of the directly simulated acceleration
用内差法合成的地震动输入情况下多点效应弱一些，但仍能体现多点效应。 - 7 . horizontal earthquake acceleration is used in this paper for slope risk analysis ; the relationship between the safety factors under the earthquake effect and non - earthquake effect is obtained . the reliability index is expressed by the safety factor
7 、将地震力效应以水平地震加速度的形式引进土坡的可靠度风险分析中，探求动力作用下土坡的动力安全系数与相应条件下的静力安全系数的关系，并以安全系数来表征土坡的可靠度。 - Based on newmark ' s step - by - step implicit integration method , the response analyses of a tunnel are performed by using viscous - spring artificial boundary under various earthquake accelerations and multiform conditions of surround rock . the seismic responses of the tunnel are calculated by changing parameters of surround rock within the tunnel some ranges . two kinds of shock absorption measures , which are setting shock layer and reinforcing surround rock are studied and shock absorption effects , applicable to cases and shock mechanism are analyze
4计算了不同地震动作用下不同的围岩材料对隧道地震反应的影响，并通过改变隧道衬砌一定范围内围岩材料的参数，计算了隧道的地震反应，分析了在隧道施工中设置减震层和注浆加固一定范围内围岩这两种方法的减震效果、适用条件及其减震机理。 - The precious method to simulate earthquake accelerations is not perfect because the points on the interface still move according to the simulated acceleration when the points " motion ends , which is obviously a paradox . if the points " velocity is not zeroized , soil ' s damage value based on shear stress ' s peaks or extrema is overestimated in multi - point input analysis . the new method ' s rationality is analyzed
以往人工合成的地震波在地震结束时即地震加速度恒为零时速度不为零，这与合成地震动是“模拟输入点从静止到运动再到静止的运动过程”这一要求不一致，同时导致时域内多点输入分析时差动力过大以至算出的损伤值过大，于是本文提出了简易的地震动速度归零化方法并分析了其合理性。
