摘要： 将摄影测量法应用于饱和土和非饱和土的三轴试验，克服了传统三轴试验在体积测量方面的困难，以获得土样的三维模型，但这一新方法还存在很多的难点。通过文献调研，从图像信息获取、土样三维模型建立和数据后处理及应用分析方面对新型摄影测量法进行介绍，概括新型摄影测量法的优点、目前的难点和研究进展。新型摄影测量法的研究虽仍处于初期阶段，但有很大的发展前景，其在非饱和土方面的应用较少，还需要后续研究工作者更深入的研究。

Abstract: The photogrammetry method was applied to the triaxial tests of saturated soil and unsaturated soil in order to overcome the traditional triaxial experiment in volume measurement difficulties and obtain a three-dimensional model of the soil sample, but it is still a relatively new method with many difficulties. Throughout the literature review, new photogrammetry methods are introduced from the aspects of image information acquisition, soil sample 3D model establishment, data post-processing and application analysis. This paper summarizes the advantages, current difficulties and research progress of the new photogrammetry methods. The research of the new photogrammetry method is still in the early stage, but it has a great development future. It has less application in unsaturated soils, and further research is necessary.

Key words: Photogrammetry, Triaxial Tests, Research Progress
