摘要
通过加筋土挡墙在列车荷载作用下的动力特性模型试验 ,得出了两种不同配筋的加筋土挡墙在两种不同频率、三种振幅荷载作用下的墙面及轨顶的累计变形随振动次数的变化规律 ,并对挡墙进行了疲劳损伤分析。这对加筋土工程具有重要实际意义。
In this paper, the relationships between the dynamic behaviour of plate of reinforced earth wall or railway track and the number of vibration cycles is obtained by model test of the reinforced earth wall with two kinds of material under the excitations of three kinds of frequencies and three amplitudes. Fatigue damnify of the reinforced earth wall is analyzed. It is important to reinforced earth engineering.
