摘要: 大瑶山隧道是正在修建的我国目前最长的双线铁路隧道,是京广复线上的关键工程,全长14.3km,最大埋深900m。本文介绍了在滑石排一号和二号斜井附近所进行的现场试验和观测结果,包括岩体初始应力,隧洞开挖后二次应力,收敛观测,以及利用预埋多点伸长计和挠度计所作的隧道侧壁和顶板位移观测。根据观测资料及有限元分析计算对隧道的稳定性进行了一般性评价。
Abstract: Dayaoshan double track tunnel with a length of 14.3 km and a highest overburden of 900m is a key item of the project doubting Jing-Guang Railway (Beijing to Guangzhou), Beijing under construction. The field results of tests and measurements performed near Huashipai inclined shafts 1 and 2 are described. Measurements of initial stress, monitoring of secondary stress, monitoring of convergence and displacements of the tunnel’s side wall and deflectometer are discussed. A general assessment of the stability of tunnel is presented according to measured data and numerical analysis.
