毕威高速路基开挖爆破对周围建筑物的影响研究
|
摘要
通过对单质点系的爆破地震响应的分析以及对爆破震动加速度和速度的相关性研究,爆破地震运动产生的加速度和最大速度是影响建筑结构震害的主要因素。通过对贵州省毕节至威宁高速公路路基开挖爆破附近建筑物的震动监测分析知,在当前爆炸药量下爆炸产生震动响应不会对周围建筑物造成危害,对指导该段路基爆破开挖施工具有重要的指导意义和现实意义。
Based on the research of the correlation between vibration acceleration and velocity,especially the analysis of blasting vibration about system of single points,we concluded that the reason of earthquake damage was determined by the maximum value of blasting velocity and acceleration.And based on the monitoring survey of the vibration of the buildings nearby the blasted roadbed of the under constructed Bijie to Weining highway in Guizhou Province,we concluded that vibration response did not harm the surrounding buildings under the current explosion dosage.It has important guiding and realistic meanings to diminish the damage of surrounding construction buildings.
