黄土地基遇水浸湿很容易发生大规模沉陷,导致建筑物结构破坏,造成不可挽回的损失。文中以引黄入晋引水工程为例,将垂直向测缝计和倾斜仪的监测数据综合进行计算,分析错动的纵向分布情况,有效地监测了隧洞的不均匀沉陷,评价了隧洞的稳定状态,也为今后类似工程的监测设计及实施提供了一定的参考。 Loess foundation wet so prone to large-scale subsidence, resulting in structural damage to the building, causing irreparable damage. In this paper, taking the Yellow River diversion project as an example, the monitoring data of vertical seam gauge and inclinometer are comprehensively calculated, the vertical distribution of displacement is analyzed, the uneven subsidence of the tunnel is effectively monitored, and the stability of the tunnel is evaluated State, but also for some similar projects in the future monitoring design and implementation provide some reference.
