摘　　要：本文在重庆枢纽《城市区岩石路堑与浅埋隧道安全控爆技术》课题组的大量监测数据和现场建（枸）筑物的安全验证基础上，总结了城区大规模土建施工中爆破开挖对城区建筑物和建筑物基础及边坡稳定的影响及评判方法，讨论了几种边坡稳定安全标准评定方法的特点和适用范围，提出了适用于城区复杂环境下边坡稳定的判断方法：边坡岩石质点临界震动速度判别法及其计算方法。In this paper, base on ChongQing hub 《 the urban area of rock cuttings and shallow buried tunnd safety controlling blasting technology）） research group has got a large number of monitoring data and the field experience, based on the blasting excavation in large-scale urban construction are summarized in the foundation of the buildings and structures in urban areas and the slope stability of the impact and evaluation method of slope stability are discussed several characteristics and applicable scope of safety standards evaluation methods, put forward the suitable for urban complex environment judgment method of slope stability, slope rock particle vibration velocity critical criterion and its calculation method.
