【摘要】 利用通用有限差分软件对重庆两江大桥渝中连接隧道爆破施工进行数值模拟分析,总结不同隧道埋深情况下的地表震速分布规律,绘制隧道沿线的地表震速峰值分区图,并结合建筑物结构安全震动控制标准对隧道沿线的地表建筑物进行安全性评价。结果表明:沿线15座地表建筑,除罗汉堂外,均符合建筑物结构安全震动控制标准。更多还原

【Abstract】 This paper carries out numerical simulated analysis for blasting construction of Yuzhong connecting tunnel between Chongqing Liangjiang Bridges by means of universal finite differential software,concludes distribution rules of surface vibration velocity at different burial depths,plots partition map of the peak values of surface vibration velocity along the tunnel,and evaluates the safety of surface buildings along the tunnel in combination with the control standard for safe vibration of building structures. The results show that 15 surface buildings except Luohan Hall along the tunnel comply with the control standard for safe vibration of building structures.更多还原
