TBM施工对地面建筑物振动影响分析

摘要

In order to know about the influential regulation and influential degree of TBM excavation upon ground building and to provide theoretical foundation for building protection in Chongqing rail construction, with the right No. 20 deck on the major route No. 1 at the section between Wulidian overpass and Wutong road as the research target, the paper tests the deck vibration condition in TBM excavation process, analyzes the test data, and obtains the influential regulation of TBM excavation upon ground building.%为了了解TBM掘进对地面建（构）筑物的影响规律、影响程度,为重庆轨道交通施工过程中的建筑物保护提供理论基础,以五里店立交至五童路段道路主1线20号右桥台为研究对象,测试TBM掘进时,桥台的振动情况,通过对测试数据的分析,得出了TBM掘进对地面建（构）筑物的影响规律。
