摘要
以软土地区填土路基段的地下综合管廊为背景,采用midas GTS有限元软件,考虑行车荷载模拟分析综合管廊路基的不均匀沉降规律。结果表明:管廊顶部和底部均存在不均匀沉降,沉降突变处均位于管廊混凝土结构与土体交界处;管廊不均匀沉降对路基的刚度变化较为敏感;通过在管廊侧壁添加垂直管廊走向的竖向混凝土板,可有效解决管廊路基的不均匀沉降。
Taking the underground utility tunnel in the section of fill subgrade in soft soil area as the background,midas GTS finite element software was used and,taking vehicle load into consideration,the rules of uneven settlement of the utility tunnel subgrade were simulated and analyzed.The result shows that,there exists settlement on the top and at the bottom of the utility tunnel,and each sudden change of settlement arises on the junction of the concrete structure of utility tunnel and the soil mass;the uneven settlement of utility tunnel is sensitive to the variation of subgrade stiffness;by means of adding vertical concrete plate perpendicular to the tunnel direction on the tunnel side wall,the uneven settlement of the tunnel subgrade may be solved effectively.
