摘要: 扬黄固海扩灌工程六干渠区段岩土条件复杂,存在湿陷性黄土、风积砂、季节性冻土等土体。为了查明这些特殊岩土的工程地质特性,进行了大量的现场和室内土工试验,并对此不良岩土特性和存在的工程地质问题进行了总结归纳,提出了相应的工程处理措施。Abstract: The conditions, such as the existence of collapsing losses, aeolian sand, seasonally frozen soil, and so on, make geotechnology become very complex in using water of the Yellow River to enlarge irrigation areas of Guyuan and Haiyuan counties through the sixth trunk dyke. So, in order to find out the engineering geological property of these special rock and soil, a large of spot and soil and extrapolated the existing problems of geology, and still brought forward corresponding treating measures of engineering.
