农历新年的脚步日益临近，秦巴山区的村落里，火红的灯笼已经高高挂起。而在西康高铁孙家河中桥施工现场，却是别样的新春图景，数十名身 着工装的建设者正冒着寒风，为一段无砟轨道做最后的浇筑。 就在不久前，这里的施工曾遭遇挑战：桥体后方紧邻的山体出现缓慢位移，导致一些前期的测量数据失效。"情况紧急，我们赶忙和设计、监理等 多方连夜会商，最终通过给山体增设抗滑桩等方式，及时止住了边坡变形趋势。"中铁十九局技术人员陈奕豪说。 更细微的挑战，藏在混凝土里。山里夜间气温常跌破冰点，新浇筑的混凝土若养护不当，强度将打折扣。于是，在中铁十九局的工地上出现了这 样的一幕：一座数十米长的蓝色保温棚横跨桥面，棚内三台热风炮持续运转，混凝土面板上不仅严实地覆盖着电热毯，还加铺了一层厚棉被。 工人们正在对西康高铁孙家河中桥无砟轨道道床进行养护。（中铁十九局供图） 中铁十九局混凝土养护工张家记说，他每天要钻进保温棚10多次，检查温度、湿度，用手背感知混凝土表面的状态。"今年尽管要在工地过年，但 看着自己修建的铁路一天天有了模样，心里也挺自豪。" 离开桥梁工地，记者一行驱车沿着蜿蜒的施工便道深入秦巴山区腹地。在一处半山平台的接触网支柱下，中铁十 ...
