Application of digital photogrammetry in tree stem analysis;

Model test of mine tunnel in stress concentration areas with digital photography-based deformation measurement technique;

The model test in combination with the non-target digital photography deformation measure technology was carried out to study the bearing capacity,soil-pressure distribution,reinforcement mechanism and deformation pattern of vertical reinforced foundation.

Digital photography is a newly developed method of recording and processing of graphic information based on digital technology and computer technology.

Experimental investigation on progressive deformation patterns of sand foundation in centrifuge test using digital photogrammetry;

An effective technique of measuring the shear bands is put forward using digital photogrammetry and image correlation analysis.

The digital photogrammetry for deformation measurement(DPDM) in geotechnical engineering is presented together with a software package developed by the authors.
