摘要
为研究TBM导洞扩挖法对紧邻建筑物的减振效果,以青岛第二海底隧道为背景,分别建立上、下台阶开挖法和TBM导洞扩挖法三种工况下的数值模型,比较分析三种工况下邻近建筑物动力响应特征,结果表明TBM导洞扩挖法减震效果较上、下台阶法更好,可为类似工程提供参考。
        In order to study the vibration reduction effect of TBM pilot-heading enlarging method on adjacent buildings,the second undersea tunnel in Qingdao was taken as research background. Numerical models of upper and lower steps excavation method and TBM pilot-heading enlarging method were established respectively under three working conditions. Then dynamic response characteristics of neighboring buildings under three kinds of excavation conditions were analyzed. The analysis shows that TBM guide tunnel expansion excavation method has better damping effect,and the conclusions were drawn to provide references for similar projects.
