偏关河河道治理堤基工程地质条件评价

Geological Condition Evaluation of Embankment Foundation Project for River Regulation in the Pianguan River

文中通过对偏关河河道治理堤基工程区域的地形地貌、地层岩性、地质构造及地震、水文地质等条件的分析,得出了结论:该区域内堤基地基承载力满足要求,地质构造较好,地震破坏较小,地下水对工程无直接影响,局部堤基在洪水期会产生渗透变形或渗透破坏,建议进行处理。

Terrain and physiognomy,stratum lithology, geological structure,earthquake,hydrogeology and other conditions in embankment foundation project area for river regulation in the Pianguan River were analyzed in this paper.The results show that:in this area, the subgrade bearing capacity of the embankment foundation could meet the requirement. Geological structure is good. Earthquake damage is small. Groundwater has no direct effect on the project.However, seepage deformation or seepage failure would occur in part of the embankment foundation during the flood period,and it is suggested to be dealt with.
