城市立交桥爆破拆除对周围建筑环境的影响
Influence of Blasting Demolition of City Overpass on Surrounding Environment
摘要
Abstract
The influence of blasting demolition of Zhangzhou east overpass on the lower foundation,optical cable of national defense and surrounding buildings was calculated by Plaxis Software.The measured wave ve-locities and deformations of foundation were compared with those calculated.It is found that the deformation of the lower foundation caused by the blasting demolition decreases as the foundation depth and the horizontal dis-tance to overpass increases;the difference between the calculated and measured maximum velocities and the de-formations of the foundation is small at some sections,however is large at other sections;the foundation de-formations of surrounding buildings and optical cable are small,and the maximum velocities are less than the safety allowable velocity.It can be concluded that the influence of the blasting demolition on these two struc-tures is within the scope of safety.关键词
