【摘要】 应用力学和渗漏耦合的方法,从隧道渗漏角度,计算并分析了隧道相对周围软土不同渗透系数比条件下的隧道沉降,分析了渗漏沉降稳定时间。计算结果表明,隧道渗漏所导致的软土地铁沉降可达20cm以上,与目前上海软土地铁隧道沉降量相当。更多还原

【Abstract】 In view of the seepage of metro tunnel, by the use of coupled flow and mechanical calculation method, the settlements of the tunnel are calculated and analyzed in the condition of different ratio of seepage rate of the tunnel to surrounding soft soil. Then the stability time of the settlements is analyzed. The calculation results show that the seepage settlements of the tunnels in soft soil in Shanghai can reach to 22cm, which is near monitoring settlement data.更多还原
