    摘要:

    采用传统方法对河床坝基进行防渗处理时,由于没有考虑到特殊地质条件,存在技术应用范围狭小的局限,因此提出一种基于GeoStudio的河床坝基防渗处理方法。选取某特殊地质条件下的河床,并对该地地质进行详细分析;根据分析结果,采用GeoStudio方法对河床的基础电性参数进行调查,对电阻率进行测试,掌握河床渗漏特殊地质介质的电性参数,得出关于河床坝基的数据;运用高密度电阻法对采集的河床坝基数据进行处理,最终根据上述步骤得出的结果,提出解决河床坝基渗漏防治措施。根据实验结果可知,所提方法对特殊地质条件下河床坝基渗漏情况分析结果和实际结果基本一致,并且运用所提方法对坝基进行防渗处理时,防渗程度在90%左右,说明所提方法防渗效果明显,能够为特殊地质河床坝基防渗工作提供有效的依据。

    Abstract:

    When using traditional methods to deal with the seepage control of river bed dam foundation, because of the limitation of narrow application scope, a method of seepage control of river bed dam foundation based on GeoStudio is proposed. According to the analysis results, the basic electrical parameters of the river bed are investigated by GeoStudio method, the resistivity is tested, and the electrical parameters of the special geological medium are mastered to obtain the data of the river bed dam foundation. Degree resistance method is used to deal with the collected data of river bed dam foundation. Finally, according to the results of the above steps, the prevention and control measures to solve the seepage of river bed dam foundation are put forward. According to the experimental results, the analysis results of seepage situation of river bed dam foundation under special geological conditions are basically consistent with the actual results, and the degree of seepage prevention is about 90% when the proposed method is used to treat the dam foundation, which shows that the proposed method has obvious seepage prevention effect and can be used to prevent seepage of river bed dam foundation under special geological conditions. Provide effective basis.
