在地铁的地下连续墙施工过程中，施工机械产生的环境振动会影响周边居民的工作生活，并对文物保护建筑的健康造成威胁。选取南昌地铁1号线子固路站—八一馆站区间为测试地点，针对地下连续墙施工常用的两种施工机械（冲击钻和成槽机）进行了地面振动的现场实测，分析了施工过程中两种施工机械引起地面振动的特性和传播衰减规律。分析表明，成槽机施工过程中产生振动较小，可用于对振动敏感的建筑物周边的施工。冲击钻会产生较大振动，距离振源60 m范围内的建筑物需要考虑环境振动问题，在施工方案制定前应评估其对周边建筑物和居民生活的影响。

During the construction of underground diaphragm walls, the vibration induced by construction machines has harmful influence on the adjacent residents and historic preservation buildings. In this paper, Nachang Metro Line1 was selected as a spot for field testing. The ground vibrations induced by two types of construction machines, impact drill and trenching machine, were measured. The characteristics and attenuation rule of the vibration were analyzed. The results show that the vibration induced by trenching machine is low, so it can be used in the vibration-sensitive areas. While the impact drill can yield large vibration, so the buildings near the vibration source will be influenced greatly by the machine. This influence should be assessed before construction planning.
