大多数路基沉陷、冲刷、坍塌、翻浆，沥青路面松散、剥落、龟裂、车辙等，都不同程度地与地表水和地下水的侵蚀有关。

The majority of subgrade subsidence , erosion , collapse , pumping , asphalt pavement ravelling , peeling , cracking and so on , are relevant to the erosion of surface water and underground water at varying degrees .

但由于黄土特殊的工程特性，常使修建在其上的公路路基沉陷、路基路面变形开裂、公路边坡塌陷等，严重影响了公路的正常运营和公路效益的发挥。

But due to special engineering properties of loess , which makes roadbed sink , roadbed and road-surface distort and craze , side slope of road subside and so on , these diseases affect seriously natural manage and benefit exert of road .

由于公路是带状构造物，往往要穿越不同的地形地质单元，有时还要通过一些不良的地质环境，经常会发生崩塌、滑坡、泥石流和路基沉陷等地质灾害。

Because highway is a strip structure , it often needs passing through different terrain units , and some cacoethes geological environment sometimes . Collapse , landslide , debris flow and subgrade settlement of geological hazards and so on occur frequently , especially in the west mountainous area in China .
