沈阳市地铁一号线地面沉降观测与分析

摘要

Shenyang Metro Line One is a major infrastructure construction projects in Shenyang city, hence, it is necessary to conduct ground settlement observation. This article describes the observation point layout principle, monitoring frequency and monitoring meth-ods. The monitoring results are analyzed. The settlement monitoring results show that the excavation of foundation pit near the subway station, and precipitation bear little influence on the surrounding buildings and ground settlement, and it will not exceed the standard limit.%沈阳市地铁一号线是沈阳市重大基础设施建设工程，有必要进行地面沉降观测。介绍观测点布设原则、监测频率及监测方法，并对监测结果进行分析。沉降监测结果表明，地铁车站基坑开挖、降水对周围建筑物及地面沉降的影响很小，不会超过规范界限值。
