【摘要】：地铁目前已经成为大中城市人们出行最主要的交通工具,随着城市规模的发展越来越快,地铁的发展需求也越来越高,虽然地铁给人们的出行带来了很大的便利,但是同时在地铁建设时期,除了带来交通的影响外,最重要的就是地铁施工过程中安全以及地铁施工过程中对现有结构的影响,如居民楼、高架桥、路面铁路等等。地铁施工过程中的安全问题依然严峻,仍然是学术界与工程界普遍关注的重点。据不完全统计,截止2015年末,中国大陆地区共26个城市开通了城市轨道交通运营,共计116条线路,运营线路总长度达3618公里,而且再从2015年至2020年新增的地铁总里程将以每年新增1000Km左右的速度增长。随着地铁规模的不断增长,各地的因为地铁施工引起的安全事故也不断增加,本文主要针对地基以岩石为主的城市在地铁施工过程中,爆破振动对周边结构物的影响为研究对象,从结构安全监测的角度出发,提出由无人值守的自动化在线监测系统替代传统的人工检测方式,从而更加实时、全面的评估结构物在地铁爆破施工过程中,对周边结构物的影响是否超过限制。自动化在线监测系统主要包括振动传感器、振动采集仪、云平台三部分组成,本文将以重点振动采集仪的实现进行描述,并整体介绍在线监测系统的实现方案。最后本套监测系统在青岛地铁R3线的施工过程中得到了应用,并取得了预期的目标和效果。
[Abstract]:At present, subway has become the most important means of transportation for people in large and medium-sized cities. With the rapid development of the city, the demand for subway development is becoming higher and higher, although the subway has brought great convenience to people's travel. But at the same time, during the period of subway construction, in addition to bringing about the impact of traffic, the most important thing is the safety during the subway construction and the influence on the existing structures during the subway construction, such as residential buildings, viaducts, Road, railway, etc. The safety problems in subway construction are still severe and still the focus of the academic and engineering circles. According to incomplete statistics, as of end of 2015, A total of 26 cities in mainland China have opened urban rail transit operations, with a total of 116 lines, with a total length of 3,618 km. Moreover, from 2015 to 2020, the total new subway mileage will increase by about 1000km per year. As the size of the subway continues to grow, the number of safety accidents caused by subway construction is also increasing. In this paper, the effect of blasting vibration on surrounding structures in a city with rock foundation is studied in the course of subway construction, and from the point of view of structural safety monitoring, In this paper, an automatic on-line monitoring system is proposed to replace the traditional manual detection method, so that the structure can be evaluated in real time and comprehensively in the construction process of subway blasting. The automatic on-line monitoring system mainly consists of three parts: vibration sensor, vibration collector and cloud platform. This paper will describe the realization of the key vibration collector. Finally, this monitoring system has been applied in the construction process of Qingdao Metro R3 line, and achieved the expected goal and effect.
