| 摘 要： | 随着城市地铁隧道埋深越来越大，全土柱计算方法已不再适用全部工程。目前国内外计算地层压力的理论很多，结果差异性很大。基于沈阳地铁下穿浑河的盾构隧道，综合分析几种深浅埋分界理论，提出实用的深埋隧道土压力计算方法。

| Abstract: | The depths of cover of subway tunnels are becoming larger; the whole-soil-column method of calculation is no longer applicable to all projects to determine the earth pressure. At present,there are many earth pressure theories at home and abroad which bring about diversified results. Based on the shield tunneling of Shenyang metro passing under the Hunhe River,this article comprehensively analyzed several theories to verify the boundary between deep and shallow tunnels,and proposes a practical method to calc... |
