摘要:
利用Plaxis软件模拟计算福建漳州市东立交桥爆破拆除对下部地基、国防光缆和周边房屋的影响,并将波速和变形计算结果与现场测量结果进行对比分析.研究结果表明:桥梁爆破拆除引起的下部地基变形量随着深度的增大而减小,也随着离桥面水平距离的增大而减小;有的断面最大波速和地基变形计算结果与测量结果较为接近,有的相差较大;爆破拆除引起周边房屋和国防光缆处的地基变形量较小,最大波速小于安全允许波速,可以认定爆破拆除对两者的影响在安全允许范围之内.
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 velocities 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 distance to overpass increases; the difference between the calculated and measured maximum velocities and the deformations of the foundation is small at some sections, however is large at other sections; the foundation deformations 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 structures is within the scope of safety.
