川道河谷漫滩地区抗浮设防水位的合理确定

Reasonable determination of anti-floating waterproof level in floodplain area of river valley

以甘肃省天水川道河谷漫滩地区为研究对象,结合工程实例,在岩土工程勘察的基础上,对研究区地下水影响因素进行分析,综合考虑大气降水、地表径流、地形地貌、地质成因、人工活动等多方面因素,最终合理确定研究区的抗浮设防水位。通过研究以期为类似川道河谷漫滩地区抗浮设防水位的确定提供参考。

Taking the flood-plain area of Tianshuichuan River Valley in Gansu Province as the research object,on the basis of geotechnical engineering investigation and combining with engineering examples,this paper analyzes the influencing factors of groundwater in the study area.Through comprehensive consideration of various factors such as atmospheric precipitation,surface runoff,topography and landform,geological origin and artificial activity,we finally reasonably determine the anti-floating fortification water level in the study area.It is hoped that this study can provide a reference for the determination of anti-floating fortification water level in flood-plain areas of similar river valleys.
