双减振沟强夯减振实验研究
Experimental Study on Vibration Reduction of Double Vibration Reduction Trench in Dynamic Compaction
摘要
Abstract
In order to study the attenuation law of dynamic vibration velocity and double vibration reduc-tion trench on its role in the reduction,two comparison experiments were carried out at the construction site,respectively,the experiment of no vibration reduction trench and single vibration reduction trench and the experiment of single vibration reduction trench and double vibration reduction trench.By detec-ting the ground vibration velocity and frequency caused by dynamic compaction in different cases,com-pared and analyzed the attenuation law of dynamic vibration velocity in three cases of no trench,single trench and double trench.Experimental results show that setting the second vibration reduction trench on the basis of the single vibration reduction trench can significantly reduce the vibration velocity,vibra-tion reduction effect of double vibration reduction trench is based on single vibration reduction trench and then cut more than 70%.关键词
