中文摘要：

为了获得高铁对邻近矿区主井的动力影响,并为回填提供依据,根据山体地形及合福高铁与邻近矿区主井的情况,建立了有无回填的两种工况模型,其中阻尼为Rayleigh模式,边界采用粘滞人工边界,列车看作移动荷载,用激振力函数来模拟。进而分析高铁荷载的频谱特性;对比竖井在有无回填下的自振频率和振型特性,研究竖井衬砌在有无回填下的位移、应力响应。结果表明：竖井回填的自振频率较竖井不回填下的大,两者前3阶振型是一样的,而在第4、5、6阶的振型不一样;竖井回填对降低衬砌的水平位移、水平应力和剪应力效果最明显;竖井衬砌受列车动载影响较大是竖井井口下方180m以内的范围。鉴于竖井下方深处存在围岩较好的约束作用,所以建议竖井回填可以不全部回填,只回填上部180m范围。

英文摘要：

According to the mountain shape and the conditions of vertical shaft adjacent to the He-fu Passenger line, two simulation models with and without backfilling were built to study the dynamic influence of high-speed rail on the adjacent vertical shaft.The train was considered as a moving load.Rayleigh damp and sticky artificial boundaries were adopted.The spectral characteristics of high-speed rail loading were analyzed by simulation of ex-citation function.The natural vibration frequency and vibration mode characteristics of the vertical shaft with and without backfilling were compared, and the response of displacement and stress of the vertical shaft lining were also studied.The results showed that the natural vibration frequency of the shaft with backfilling is higher than that with-out backfilling.The first, second and third mode shapes are the same, but the fourth, fifth and sixth mode are dif-ferent.The reduction of horizontal displacement, horizontal stress and shear stress are the most obvious with back-filling.The influence of the railway dynamic load on the shaft lining is larger in the range from the mouth to the 180 m depth below the surface.In view of the better restriction effect of the deep surrounding rock on the shaft, it was suggested that the vertical shaft can be backfilled not all, but just the upper 180m range of the shaft.
