摘要

摘要: 以西安地铁3号线小寨区间近距离平行地裂缝的特殊工程场地为工程研究背景，基于有限差分原理的FLAC3D数值模拟方法，研究地震和地裂缝场地沉降耦合荷载作用时地铁隧道地震动力响应问题。结果表明：地表峰值加速度在地裂缝附近取得最大值，且PGA放大系数由地裂缝向两侧逐渐衰减；地裂缝隧道场地水平地震土压力增量随着输入地震波峰值加速度PGA的增大而增大；上盘的水平土压力增量明显大于下盘，且曲线在地铁隧道处存在一个峰值；隧道结构中，左拱腰处水平土压力相比右拱腰及拱顶处水平土压力较大，且拱底与左拱腰处水平土压力一致；隧道拱顶处水平土压力增幅量明显，且隧道处水平土压力增量随输入地震波PGA的增大而增大，左拱腰处的水平土压力地震响应大于右拱腰，但增幅小于右拱腰。

Abstract: The part of Xi'an Metro Line 3 in Xiaozhai which is parallel to ground fissure is taken as the research engineering. The dynamic response of subway tunnels during the coupled load of earthquake and ground fissure sedimentation was studied by the FLAC3D numerical simulation which is based on the finite difference principle. The results show that the peak acceleration of ground reaches maximum near the ground fissure. And the magnification coefficient of PGA gradually decays from the ground fissure to both sides. In ground fissure tunnel horizontal earth pressure increases with PGA.The increase of horizontal earth pressure on the hanging wall is obviously larger than that on the footwall and the curve has a peak at the tunnel. The horizontal earth pressure at the left arch waist is greater than that at the right arch waist and the top in the tunnel. The horizontal earth pressure at the bottom is consistent with that at the left arch waist. It obviously shows that the horizontal earth pressure increases at top. Horizontal earth pressure increases with PGA at the tunnel. The horizontal earth pressure at the left arch waist is greater than that at the right arch waist, but the increase is smaller than that at the right arch waist.
