深孔注浆在地铁邻近建筑物控制沉降的应用

Application of Deep Hole Grouting in Controlling Settlement Deformation in Construction of Subway Adjacent Buildings

以北京某地铁暗挖PBA车站小导洞旁穿建筑物为例,通过对车站一侧边导洞采取深孔注浆措施与另一侧边导洞未采取深孔注浆措施的沉降监测数据比对,基本得出了通过采用深孔注浆措施能够有效地减小对建筑物的变形影响,在以后类似的地铁施工穿越建筑物风险源具有指导意义。

In this paper,taking a small guide tunnel of a subway station in Beijing as an example,by comparing the settlement monitoring data of one side of the station with that of the other side,it is concluded that deep hole grouting can effectively reduce the influence on the deformation of the building.It has guiding significance for similar metro construction to cross the building risk sources in the future.
