荒地镇防洪工程地质条件分析与评价

Analysis and evaluation of geological conditions of flood control project in Huangdi Town

通过对荒地镇防洪堤项目防洪区工程地质条件及存在问题进行了分析,结果表明,工程区地质构造稳定,土层渗透变形破坏形式为流土,防洪堤采用就近粉细砂、粉土、黏土作为填筑料;地下水埋深较浅,需做好排水措施。

The paper studys the engineering geological conditions and existing problems of flood control region by sampling tests and calculation analysis.The results show that the geological structure of the project area is stable.The destructive pattern of seepage deformation of the soil layer is soil flow.It is suggested that the allowable hydraulic slope should be 0.48.The flood protection embankment can use the nearest fine sand,silt,clay as the filling material.The groundwater has a shallow depth and the drainage measures should be taken.
