摘要
在城市建筑物密集区进行振动沉管施工,引起震动对周围环境的影响已成为地基处理施工中一个突出的问题,通过对某项工程水泥粉煤灰碎石柱(CFG)桩施工振动对周边建筑物影响的测试和分析,对地基处理方法的选型及如何有效减轻和控制施工振动对周围环境的影响,均具有一定意义。
The vibration caused by the construction of vibrancy immersed tubes in an urban building compact district has to effect on the ambient environment of construction sites, which is one of prominent problems in the foundation construction. Based on the test, measurement and analyzing results of vibration by the vibro piles in an engineering project, it puts forward some lectotypes of foundation treatment and an effective method of lessening and regulating influence of vibration on the ambient environment engendered by the construction of vibrancy immersed tubes, which are of some significance.
