摘要
通过有限元软件,对浅基础条件下建筑荷载对隧道的影响进行了分析,其中主要包括土层性能、隧道埋深、建筑与隧道的水平距离、建筑荷载的大小等因素,分析结果表明:土层的压缩模量越大,浅基础荷载作用对隧道的影响越小;随着隧道埋深的增大或随着浅基础与隧道水平距离的增加,浅基础荷载作用下对隧道的影响均逐渐减小。
Through the finite element software, this paper analyzed the influence of building load to tunnel under shallow foundation situation, in- cluding the soil layer performance, tunnel buried depth, the horizontal distance of buildings and tunnels, building load size and other factors, the analysis results showed that： the soil compression modulus more larger, the influence of shallow foundation load to tunnel more smaller, with the increase of tunnel buried depth or the increase of shallow foundation and tunnel horizontal distauce, the influence of shallow [bundation load to tunnel decreased gradually.
