小块体地质力学模型在一定程度上能够反映岩体的非连续、多裂缝特征,但是采用常规的接触式位移测量法使模型试验的应用受到一定的限制。本文作者在该种模型试验中,应用白光散斑照相法进行模型位移场的测量,取得了成功的经验。 The small block geomechanical model can reflect the discontinuous and multi-fracture characteristics of rock mass to a certain extent. However, the application of the conventional contact displacement measurement method to the model test is limited. In this kind of model test, the author uses the white light speckle photography method to measure the displacement field of the model and obtains the successful experience.
