| 摘 要： | 边坡时间-位移曲线理论上单调,但是监测到的常是振荡起伏的,即监测显示侧向位移方向发生变化。本文指出随机噪声是振荡的主要原因,而起伏才是边坡发展的真实状态。两者相比,振荡的频率远大于起伏,而振幅则远小于起伏。并结合实例指出,边坡表层或内部协调变形、水及人类活动产生的加卸荷作用及温度变化引发的热胀冷缩效应等都可以引起监测曲线的起伏。这对分析监测曲线的振荡起伏现象提供了帮助。

| Abstract: | The monitored displacement of the slope is usually oscillated and fluctuated, i.e. the direction of the lateral displacement changes with time. This paper analyzes the similarities and the dissimilarities in the oscillation and fluctuation of the time~displacement curve with some examples. It is found that fluctuation was caused by the slope condition, water, human activity and temperature. The finding can provide useful information on the analysis of the oscillation and fluctuation of the monitored displacement curve for slopes. |
