摘要
本文从地壳、地基和堤坝三系统对黄河下游悬河做了初步工程地质研究,对悬河的地质背景,河道稳定性的地学控制因素和地质工程治理对策有了较系统的认识。明确以稳定现有河道(延寿)为目标,采用地质工程和水利工程相结合的大系统环境治理方法,是消除悬河威胁解决中国这一重要环境岩土工程问题的可行途径。
A preliminary engineering-geological study on the suspended river in the lower reaches of th Yellow River has been made from three systems, i. e. the earth's crust, foundation and embank ment. Through the study the authors have got systematic knowledge of suspened river, control ling factors of channel stability and geo-engineering regulation. Defining the aim of stabilizing pressent channels and taking the method of combining geo-engineering works with the water conservancy project are practicable approaches for eliminating the threat of the suspended river.
