摘　　要：在大连疏港高速公路松树岭大跨度砂质粘土隧道施工期间,对洞内拱顶下沉、边墙水平收敛、边墙脚沉降以及地面沉降等进行了监控量测。文章介绍了该隧道施工监控量测的基本方法,对监测结果进行了分析,总结出了该类隧道及地表沉降的基本规律,对类似工程的施工监控量测有一定的参考价值。In the construction of Dalian Songshuling large-span highway tunnel passing through sandy clay, monitoring was carried out for crown settlements, horizontal convergences of side walls, settlements at side wall abutments as well as surface subsidence. The paper introduces the main methods of monitoring for the tunnel construction, analyzes the results of measurements, summarises the basic law of settlements.
