摘要
模型试验中常用物理或机械的方法测量位移,该文利用数字近景摄影测量方法对位移进行了测量,并对位移的发生做了假设检验,极大地降低了将由误差引起的位置变动看作发生位移的概率。最后对边坡滑移的物理模型试验进行了位移量测。
Using digital camera (non-metric or metric) to measure displacement is a non-contact, high-speed and easy-operating method according to the principle of digital close-range photogrammetry. The result showed that the simplified 2D model is more convenient and with higher precision.Finally,the displacement measurement has been conducted for a physical model test of slope slide.
