摘要
穿黄工程是南水北调中线的咽喉工程。沿线地质环境条件复杂。现状条件下,场区黄河南岸段多发滑坡、崩塌、潜蚀塌陷、地裂缝等地质灾害；黄河河床及河漫滩段存在砂土液化问题；黄河北岸清风岭段存在黄土湿馅问题。工程建设过程中存在黄土高边坡失稳问题,可能引发崩塌、滑坡等地质灾害,砂土液化、黄土湿陷、潜蚀塌陷、不均匀沉陷及地裂缝等可能使工程遭受危害。工程建设过程中需针对不同的灾害类型采取适当的预防或治理措施。
. The Yellow River-Crossing project plays a decisive role in the national key project＂south-to-North Water Diversion＂. During construction, the unstable loess high slopes might produce geological hazards like collapses, landslides, liquefaction, loess collapses, cave-in caused by sub-erosion, uneven subsidence and land fissures, which might threaten the project. Proper measures should be taken to cope with different geological hazards.
