摘　　要：针对新宝塔山隧道进口边坡及房屋稳定性,根据具体情况进行了房屋爆破振动影响和边坡静力分析。振动影响分析采用了场地地震效应工程勘察方法对爆破振动速度做了放大系数修正;并通过整体稳定和局部稳定性验算进行了静力分析。分析中根据工程条件,选择了适合地形地质的合理方法,对隧道开挖引起的边坡稳定性分析具有一定的参考价值。According to the specific conditions of the slope and house stability at the new Baota tunnel entrance,an analysis of the house demolition vibration influence and slope static is carried out.The site earthquake effect engineering survey is adopted for the vibration influence analysis to revise amplification factor for the blasting vibration velocity.Through the whole stability and partial stability calculation,the static analysis is checked.Based on the project conditions,choose a reasonable method suited for geological landform in the analysis,which is of a certain reference for tunnel excavation-caused slope stability analysis.
