摘要
对采用深孔重夯法加固湿陷性黄土地基所产生的振动影响进行了试验,归纳出了振动在湿陷性黄土中的衰减规律,分析了加固振动对毗邻建筑及人体舒适度的影响,同时,分析了黄土振陷产生的原因及条件。试验及分析结果表明:深孔重夯的施工振动在湿陷性黄土中的衰减迅速,一般不会对毗邻的建筑产生破坏性影响,湿陷性黄土也不会产生振陷,但可能会影响一定范围内人的舒适度。
The effect of vibration is tested to reinforce humid-fallen loess foundation with down hole dynamic compaction. The attenuation regularity of vibration wave in the ground of humid-fallen loess is concluded, the effect to the adjacent building and the comfortableness of human body was analyzed, at the same time, the reasons and conditions of vibration-subsidence are studied. The result of experiment and analysis demonstrated： Due to the swift attenuation of vibration caused by DDC in the ground of humid-fallen loess, there is no destructive effect to adjacent building,and no vibration-subsidence to humid-fallen loess, but it is possible to affect the comfortableness of human body.
