摘要:

为了探究潮位变化与越江盾构隧道的沉降和收敛变形之间的关联性,采用数据统计分析、相关性分析和周期性分析方法,对上海某越江盾构隧道的监测数据与同时期隧道上部的潮位变化进行研究分析。研究表明: 1)江中段隧道在潮位变化的作用下产生均匀沉降,其波动性与潮位起伏具有近似的周期性; 2)陆域段隧道沉降变化的波动性程度与河流的距离有关; 3)潮位变化引起隧道管片断面的横径和竖径产生循环的收敛变形,其横径收敛变形大于竖径收敛变形。以上研究可为越江盾构隧道设计、施工和运维提供参考。

Abstract:

The monitoring data of a rivercrossing shield tunnel in Shanghai and the tidal fluctuation above the tunnel are analyzed by data statistical analysis method, correlation analysis method and periodicity analysis method, so as to learn the relationship between tidal fluctuation and deformation and convergence of rivercrossing shield tunnel. The results show that: 1) The even settlement would occur at tunnel section in river; and the settlement fluctuation and tidal fluctuation show similar periodicity. 2) The settlement fluctuation of tunnel section on land is related to the distance between tunnel and the river. 3) The tidal fluctuation induced cyclic convergent deformation of transverse diameter crosssection of tunnel segment is larger than that of vertical diameter of crosssection of tunnel segment. The study results can provide reference for design, construction and maintenance of rivercrossing shield tunnel.

Key words: crossriver shield tunnel, tidal fluctuation, operation period, tunnel settlement, tunnel convergence
