地质条件、隧道埋深对振动波的传播影响较大,在离开隧道轴线一定距离存在一个振动放大区,在此区域内地面振动强度有所增大。 - Through analyzing all kinds of construction methods of building metro station under shield driven method in many countries , this paper studies the construction technique ( method ) of building metro station under shield driven method , taking in guangzhou no . 3 metro line , and linhe xilu station as the actual object . according to station class , function and topography and geology , the station schemes of twin - bore tunnel ( island ) , firstly , three parallel tunnels ( island ) , tri - bore tunnel ( island or side ) and four parallel tunnels ( island or side ) are proposed . secondly , the shape and main parameters of station structure on two schemes are analyzed with load - structure mode , for different overburden depth of tunnel and lining thickness , etc . thirdly , the construction process is simulated in 2d fem . ,
根据建站的规模、使用功能及站位地形地质条件,提出了两连拱结构岛式站台车站、三条平行隧道岛式站台车站、三连拱结构岛式和侧式站台车站以及四条平行隧道岛式和侧式站台车站方案;采用荷载?结构模式,对四种方案的主体结构的形式和重要参数进行分析研究,分不同的埋深、衬砌结构厚度和拱形结构的拱跨比进行了多组数值计算;采用平面有限元方法对四种车站结构的开挖施作过程进行了模拟分析。 - With the increase of lateral pressure modulus , the magnitude of principal stress decreases and the direction of it is hardly changeable ; with the increase of the angle between the direction of the maximal horizontal principal stress on magnitude and the fault bearing , the magnitude of principal stress increase and its direction can hardly change ; with the increase of the elastic modulus of rocks , the magnitude of principal stress increases and the direction changes more ; with the increase of pr , the magnitude of principal stress decreases and the direction changes more ; with the increase of lateral pressure modulus , the principal stress at hance , the tress at topmost arch , bottom arch and principal stress at lateral arch decreases , with the increase of the depth of tunnel , the stress of surrounding rock also increases , and the poorer the quality of surrounding rock is , the little its principle stress is
分析得出,随着侧压力系数的增大,主应力量值减小,主应力方位难改变;随着与断层走向的夹角增大,主应力量值增大,应力方向难改变:随着岩石的弹性模量的增大,主应力量值增大,方向变化越大;随着泊松比的增大,主应力量值减小,方位变化越大。随着侧压力系数的增大,顶、底拱处的各应力值增大,拱腰处的主应力减小,剪应力增大,侧拱处的各主应力减小,同一侧压力系数的条件下围岩质量越差,各应力值也越小;随着洞室埋深的增加,围岩压力也增大,围岩质量越差,其应力值也减小。
