| 摘 要： | 由于正在修建的高层建筑施工影响，使既有电缆隧道（从在建高层建筑物下方穿过）受力条件非常复杂。为了防止电缆隧道产生较大的变形，制定了隧道监测方案。通过对隧道进行收敛变形和衬砌表面应力量测并分析量测数据，得出隧道围岩具有变形小、收敛变形在上部建筑封顶后逐渐缓和、拱顶下沉较水平收敛变形大的特征，通过监测得出结论，虽然上部建筑施工对隧道产生一定影响，隧道结构仍处于安全状态。

| Abstract: | Due to the influence of the high-rise building under construction,the existing power cable tunnel that passes underneath the high-rise building is subject to complex loading conditions.In order to avoid serious deformation of the power cable tunnel,monitoring measurement plan is worked out.Convergence monitoring and lining surface stress monitoring are made for the tunnel and the monitoring results are analyzed.The monitoring result shows that although the construction of the high-rise building above the tu... |
