Study on Dynamics Equation Approximation of Blasting Demolition of Structures(1)

FU Jian-qiu 1,2,WEI Xiao-lin 1,2,WANG Xu-guang1(1.Beijing University of Science and Technology,Beijing 100083,China;2.Guangdong Hongda Blasting Engineering Co Ltd,Guangzhou 510055,China)  
The numerical solution,velocity analytical solution and approximative solution of dynamics equation,which describe that overhanging rooted body with plastic joint end is whirled and vertical rooted body with basis plastic joint is sloped down,are studied in this paper.The different between numerical and approximative solution is about 5%.Analytical and approximative solution formulas can be applied in different initial condition.It is solved in moving above and on ground that the beam is whirled in single span,the beams are sloped down and disintegrated by gradual span,the shear wall and chimney are topped by blasting demolition.The relationship among moving posture of building and its coefficients is presented.Consequently,the principle of moving posture of building is easy to be explored and demolishing scheme can be optimized and calculated conveniently.
