摘　　要：针对大连地铁109标段施工过程进行监控量测,分析施工过程中边坡稳定性问题.主要采用电子水准仪二等水准测量方法对边坡沉降进行观测,并采用全站仪对边坡水平位移进行施工过程中的监控量测,全面分析了施工过程中的沉降及水平位移数值变化规律.结果表明:明挖基坑坡顶监测点累计最大沉降值为9.2 mm,最大水平位移为17.8 mm,均符合规范要求,施工过程中边坡基本稳定,能够保证安全施工,可为同类工程施工监测提供参考.The construction process monitoring of Dalian metro 109 bid is studied, and the problem of slope stability is analyzed during the process of construction. The electronic level second level method and total sta- tion instrument are used for slope settlement observation and horizontal displacement of slope monitoring meas- urement in the construction process. A comprehensive analysis of the construction process of the settlement and horizontal displacement numerical variation is studied. The results show that the accumulated maximum settle- ment value accumulated of the slope monitoring points is 9.2 mm, and the maximum horizontal displacement is 17.8 mm, which meet with the regulatory requirements. The slope is basically stable in the process of the con- struction with an ensured construction safety.
