强夯振动对周边环境的影响研究
|
摘要
为研究强夯振动对周边环境带来的影响,对某高速公路工程高填路基强夯处理作业振动进行试验监测,分析振动强度、Z振动级(VAL)、地震烈度等3个指标。利用origin软件对试验数据进行非线性拟合,得出强夯振动地面速度、加速度随距离衰减的公式,并据此分析其衰减规律。结果表明,连续强夯施工振动对周边建筑物虽无破坏性影响,但对建筑物的非承重部位会有一定影响,使附近建筑物里的人产生不舒服感。为减少强夯振动带来的此类影响,应开挖减振沟。
To study the impact of dynamic compaction vibration on surrounding environment,a certain freeway section 's embankment fill compaction handling high vibration test monitoring was carried out.Three indexes were analyzed. They are vibration intensity,Z VAL,and seismic intensity values. Nonlinear fitting of experimental data was made by using the origin software. Calculation formulas were obtained for ground speed and acceleration attenuation. The attenuation process was analyzed. The results show that continuous dynamic compaction vibration has no devastating impact on surrounding buildings, that vibration affects adversely non-load-bearing parts of building,and it can make the residents living in the nearby buildings produce uncomfortable feelings,and that in order to reduce such effects,a damping ditch should be dug.
