宝兰高铁甘肃段7大工程难点

宝兰高铁甘肃段全线地质条件十分复杂,湿陷性黄土、滑坡、崩塌等不良地质类型遍布,极大地增加了施工难度。工程建设的难点主要有七个方面。宝兰高铁甘肃段新建特大、大中桥81座,隧道60.5座,桥隧全长占正线的91.6%。

1、工程地质特殊,具有“四最一强”的工程地质环境特色。

宝兰高铁线路经过的地形地貌单元为关中(渭河)盆地区、南陇山和西秦岭北缘过渡带的高-低中山区,天礼盆地低山丘陵区,黄土高原沟壑、梁峁区,黄河河谷兰州盆地区。具有黄土湿陷性(尤其是自重湿陷性)最强、黄土陷穴最发育、黄土高原地区滑坡地质灾害最严重和发育最密集以及沿着天水—兰州地震带和东西向展布的渭河地震带活动频率高、强度大,形成了“四最一强”的工程地质环境特色。

2、不良地质和特殊岩土分布广,存在六大工程地质风险,工程风险高。

宝兰高铁沿线的不良地质类型以黄土滑坡、黄土泥岩滑坡、错落、危岩落石、黄土陷穴为主,泥(石)流、地震液化次之,特殊岩土主要有湿陷性黄土和具有膨胀性的第三系泥岩。工程建设中存在六大地质风险因素(黄土地基沉降的风险、黄土陷穴风险、滑坡复活等斜坡不稳定风险、泥石流及堵沟风险、极软岩隧道大断面开挖风险、强地震风险),施工安全风险大,同时大临设施和工程建设不当也可能诱发滑坡等次生灾害的发生。
