摘要
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。
Irredeemable losses are often caused when the building structure is damaged by extensive settlement of the collapsible loess foundation. Illustrated by the case of the Yellow River Diversion Project, the data of joint meter and inclinometer are synthetically calculated and the longitudinal distribution of displacement is analyzed. The differential settlement of the tunnel is monitored effectively and the. stability of the tunnel is evaluated, providing some reference for monitoring design and implementation of similar projects.
