Application of High Density Electrical Method in Detecting Hidden Leakage of Levee during Flood Season
High water levels and high permeability pressure will cause the expansion of levee leakage defects or aggravation of hidden dangers during the flood season.Rapid and accurate emergency investiga-tion of hidden dangers of levee leakage is an important measure to guide scientific flood prevention and en-sure safe during flood season.In view of the leakage defects and hidden dangers such as piping,dispersion,and levee-crossing buildings,high-density electrical method site test is carried out,and the electrical struc-ture of levee during flood season is obtained.Through the comparison test,the electrical differences be-tween different leakage defects and no significant defects of levee are obtained.Based on this,high density electrical methods are used to investigate hidden dangers in the Tianjin Jinghai section of Ziya River right levee,especially in the section where the Ziya River merges into the Duliujian River.The division of hid-den leakage areas and potential risk areas provides important technical support for ensuring the safety of levees during the"23·7"catastrophic flood in the Haihe River Basin.
