黄土地区穿越多滑动面断层浅埋暗挖隧道振动台试验研究
Vibration Table Test Study on Shallow Buried and Underground Tunnels Crossing Multiple Sliding Surface Faults in Loess Areas
摘要
Abstract
Xi'an is located in the Fenwei seismic zone,and there are many large active faults around it,and many tunnels intersect inevitably with the faults.In view of this,according to the multi-slip surface fracture of Xi'an Metro Line 9 passing through Lishan Mountain as the prototype,and based on a large-scale shaking table test carried out,the failure and deformation law of multi-slip surface fault site and shallow buried tunnel under far-field ground motion are explored.The results show that under the action of the earthquake,the damage range of the hanging wall is larger than that of the foot-wall,but the damage degree is smaller;the time-history curve of the settlement displacement of the surface presents an in-verted S type characteristic;at the soil on both sides of the main fault,the relative settlement displacement between the hanging wall and the footwall is the largest.The acceleration response of the tunnel shows an obvious amplification effect of the hanging wall.The results show that the damage range of the hanging wall is smaller than that of the footwall,but the damage intensity of the hanging wall is larger.The experimental results can provide some basis for the construction of similar projects in the future.关键词
