摘要
黄土地区冲沟发育密度大，沟底下切、侧向扩展、溯源侵蚀迅速，且常伴有不良地质现象发生，是管道建设的主要难点之一。本文根据黄土地区冲沟的特点，结合近几年的工程实践的经验，论及了管道穿跨越黄土冲沟位置的选择原则、穿跨越形式和方法以及岩土工程处理措施。
Loess area is one of major difficult zones in pipeline construction with great development density of gulch,down-cutting gulch bottom,side expansion, rapid headward erosion and bad geologic tendencics to be followed. This Paper expounds selection principle of pipeline crossing places,crossing pattern and method,and puts forward treatment measures for rock and soil according to gulch features in loess area and in combination with practical experience obtained from project construction in recent years.
