受山西省水利厅引黄办公室的委托,笔者与我系部分师生于1981—1982两年在晋西北偏关、平鲁和朔县进行了北引黄工程扬水方案总干线规划阶段的工程地质勘查,主要工作是1:5万综合性工程地质测绘。勘查地段西自黄河之畔,沿其支流偏关河朔源而上,穿越黄河流域与海河流域之分水岭管涔山脉（吕梁山脉北延部分）而进入雁同盆地。该宏伟的水利工程主要工程型式是输水隧洞,在跨越沟谷地段则需修建渡槽等交叉工程。由于晋西北系黄土高原区,黄土的湿陷特性将严重影响交叉工程的稳定性,是该工程的主要工程地质问题之一。为此,笔者在指导学生作毕业论文和编写生产报告过程中,对黄土的工程地质特性进行了初步研究。
Commissioned by Shanxi Provincial Department of Water Resources Yellow River Administration, the author and I part of the teachers and students in 1981-1982 two years in Shanxi Northwest off, Pinglu and Shuo County conducted the North Yellow River pumping scheme general mains planning phase engineering geology Exploration, the main work is 1: 5 million comprehensive engineering geological mapping. The exploration area west of the Yellow River, along its tributaries off the watershed, passes through the watershed of the Yellow River basin and the Haihe River basin (the northern extension of the Lvliang Mountains) and enters the Yan-Tong basin. The grand project of water conservancy works is a water diversion tunnel. Crossing projects such as aqueducts are required across the valleys. Due to the loess plateau area in the northwestern Shanxi Province, the collapse characteristics of loess will seriously affect the stability of cross-over projects and is one of the major engineering geological problems of the project. Therefore, in the course of instructing students to do graduation thesis and writing production report, the author carried out a preliminary study on engineering geological characteristics of loess.
