摘要
上海城市轨道交通建设高速发展,已经形成了覆盖中心城区、相互交织的轨道交通网络。轨道交通相互穿越是地铁隧道施工中的技术难点,对地铁穿越时的变形监测也提出了高要求,但目前尚未有较好的方法满足施工监护要求。本文采用电子水平尺和静力水准仪综合应用于上海地铁隧道穿越工程中的沉降监测,较好地解决了短距离沉降监测中的关键技术问题,在实践工程中取得了较好效果。
With high-speed development of urban rail transit construction,interlace of metro transportation network has been formed,which covering central city.Crossing subways each other is a technical difficulty in subway tunnel construction.Meanwhile,this also presents higher request.But at present some methods can＇t satisfy construction monitoring.The paper intergrated static force level and electronic clinometer into subsidence monitoring in subway tunnel crossing projects in Shanghai,and solved some key technology for monitoring subsidence of short distance tunnel.This method has obtained better effects.
