Through simulation of the real process of thomcolumbar burst fracture and use of modem dynamics techniques, the present study was (1) to investigate the kinetic relationship between structural damage and impact energy absorption and dynamics mechanism of thoracolumbar burst fracture by quantitative analysis of various injured segments;(2) to explore the instability mechanism of L1 vertebral burst fracture and its injury threshold by three-dimensional analysis of the injured segment with stereophotogrammetry in combination of transient physical parameters, anatomy and image;(3) to explore the corresponding relationships between impact energy, geometry parameters and biomechanics by geometry and biomechanical analysis of thoracolumbar burst fracture, which may provide an objective standard for evaluation of spinal injury severity and experimental evidence for adoption of biomechanical treatment in clinic;(4) to evaluate the fixation effect of different instruments and the effect of intervertebral bone graft on segment fixation by analysis of the threedimensional stability of different internal fixation instruments and their decompression of the spinal canal, which may provide experimental evidence for therapeutical selection for thoracolumbar burst fracture in future; and finally to investigate the effect of various instrument fixation on dynamical characteristics by comparison and quantitative analysis of frequency and amplitude responses, which may provide certain theories and experimental evidence for application of vibration test to judge the stability of the spine.

Fracture styles are consisted mostly of structural fracture, which not only make up the principal permeability contributor, but also control porosity distribution in the vertical and planar section. The matrix porosity has good correlation with the fracture's development in the Carboniferous bioclastic limestone member. High porosity zones are commonly found in fracture well developed parts such as structure axes, low porosity zones in less fracture structure nek.

Aiming at the frequent occurrence of drill-string fracture during gas drilling in the Puguang gas field, this paper, based on the statistical analysis of accidents on fields, makes in-depth investigation into the origins of drill-string accidents in aspects of peculiar drilling medium, different rock-breaking methods, and the vibration of drill string during the drilling process. Through macro, micro and material analysis of the fracture surface of drill string, the law of drill-string failure due to fracture is discovered and the fatigue fracture is found out to be the main type of drill-string fracture.
