摘要
对新生界上第三系(N)岩性的认识有岩类、软岩—硬土和硬土类三种观点。通过黄河西霞院、漳河岳城水库和万家寨引黄入晋三个大型水利工程对上第三系的工程地质进行研究,认为应属于硬土类。这对保障工程地质勘察、工程设计、工程施工及安全运行起到重要作用。对于其它类似工程,宜从上第三系地层岩性、工程地质性质入手,具体判定其岩土类型。
The viewpoints on Neogene lithology in Cenozoic can be divided into three kinds as rock,soft rock-hard clay and hard clay, the authors believe that it belong to hard clay through the research on Neogene engineering geology based on three large-scale hydraulic projects as Xixiayuan Project on Yellow River, Yuecheng Reservoir on Zhanghe River and Wanjiazhai Yellow River Diversion Project. It plays an important role in protecting engineering geological survey, engineering design,construction and safe operation. In regard to other similar projects, it should judge the type of rock and soil specifically beginning with Neogene formation lithology and engineering geological property.
