根据建筑物拆除爆破失稳原理,对桥礅柱定向倒塌控制爆破拆除试爆时产生后坐进行力学分析,得出试爆产生后坐的主要原因是保留支撑截面瞬间强度不够,调整主爆相关参数,使主爆达到预期效果。 相似文献

Geophysical bore-hole data represent the physical properties of rocks, such as density and formation lithology, as a function of depth in a well. Properties of rocks are obtained from gamma ray transport logs. Transport of gamma rays, from a 137Cs point gamma source situated in a bore-hole tool, through rock media to detectors, has been simulated using a GEANT4 radiation transport code. The advanced Compton scattering concepts were used to gain better analyses about well formation. The simulation and understanding of advanced Compton scattering highly depends on how accurately the effects of Doppler broadening and Rayleigh scattering are taken into account. A Monte Carlo package that simulates the gamma-gamma well logging tools based on GEANT4 advanced low energy Compton scattering (GALECS). 相似文献
