| Abstract: | This thesis researched the case that a metro station transfer channel and mining-method tunnel would pass through a major protected building from either side. First of all,the influence of excavating the channel and tunnel on the adjacent protected building was analyzed by numerical simulation method.On this basis,the comprehensive strengthening and protection measures for the adjacent protected building were put forward as follows: piling into the ground to form some shelter pile-foundations for the adjacent protected building,and grouting into the channel and tunnel to strengthen them. And then based on above-mentioned strengthening and protection measures,the sequence of excavating the channel and tunnel on either side of the adjacent protected building was studied,which would have influence on the strengthening effect. |
