摘　　要：建国前修建的宝天铁路是严重的病害铁路。号称陇海铁路的"盲肠",主要受渭河区域性大断层的影响,沿线滑坡、泥石流等病害发育。增建二线绕避严重不良地质区,选择渭河两岸的有利地形、地质条件,通过几个实例,说明线路多次跨越渭河是恰当的。The Baotian railway called‘caecum’ of Longhai railway is a serious lesion railway before the PRC founding,which well-developed landslides and dobris flows.It was also influenced by regional faults of Weihe river.The Baotian second railway detoured and bypassed the serious poor geological section.The arti- cle explained the railway line stride across Weihe river for many times by several living examples,which se- lected the advantage landscape and geological condition along both Weihe river sides.
