摘要
将航空摄影测量中常用的照片解析方法，应用于软岩巷道模型试验的位移测量，证实了采用普通照像机且忽略非线性误差所得结果能够满足实验精度需要．该法对动态的和非接触的测量具有同样的应用前景．根据实验结果得出的软岩巷道变形破坏规律，对于采取合理的支护措施具有积极的意义．
Photo analytic method usually used in aviation photography measurement, it was applied in displacement measuring of model experiment of soft rock tunnel. It confirmed that the result can meet the demand of experiment accuracy which use popular camera under omitting non-liner error,it has same application perspective to dynamic state experiment and non-contact measuremot. The priciple of deformation has positive signification tO select proper enhancement method.
