Related research on hydrogeological issues in geotechnical engineering investigation
To study the hydrogeological problems in geotechnical engineering investigation.Firstly,in the flow state of the expression layer,Darcy's law is applied to provide the transverse and vertical permeability coefficient values.According to the actual engineering demand and the direction of seepage flow,the appropriate equivalent permeability coefficient is selected.Then,considering the permeability of the strata,a reasonable survey interval is determined.Use measuring tools for specific water level measurements and remove errors regularly to ensure the accuracy of measurement data.With the increase of collapsible amount,the total thickness of collapsible soil remained at 22-25cm,and the result was in line with expectation.The detailed information of the soil quality of the site can be accurately obtained to eliminate the hidden danger in the construction process.
