土石方爆破工程振动对人体舒适度影响的评估及运用

Evaluation on the Influence of Earth-rock Blasting Engineering Vibration on Human Comfort

根据目前的国内外爆破振动对人体影响的标准以及时域滤波器技术,结合云南省蒙自绕城高速公路雷公哨段爆破开挖工程案例,确立了一个有效的爆破振动舒适性评价方法,并对该案例评价过程和评价结果做了阐述与验证。其结果表明,现实状况与这种评价方法所得到的结论是相一致的;同时从结论中我们还看到,即便是一次很小的、不能够导致损伤建筑物的爆破振动,居民也会有抱怨、甚至投诉。因此,在爆破施工时,在保证施工安全,正常的情况下要充分以舒适性研究的有关成果及观点为依据,尽量减少现场施工对周边居民的不利影响,从而避免矛盾冲突的产生。

According to the current domestic and international standards of blasting vibration＇s impact on human and time domain filter technology, combined with blasting excavation engineering cases of Yunnan Mengzi city highway Tripterygium wilfordii section, established an effective evaluation method forv blasting vibration comfortablity and made elaborate and verification about this case＇s evaluation process and evaluation results. The result shows that the reality is consistent with the conclusion of this evaluating method; and we also see from the conclusion, though a little, with no damage to building blasting vibration can lead to residents＇ grumble, and even complain. The result shows that the reality is consistent with the conclusion of this evaluating method; and we also see from the conclusion, though a little, with no damage to building blasting vibration can lead to residents＇ grumble, and even complain. Therefore, when blasting construction, under ensuring construction safety and normal circumstance,we should fully based on related results and opinions of comfortablity studies,minimize site construction＇s adverse effect on surrounded residents, thereby avoiding contradiction and conflict.
