Abstract

The invention provides a test method for obtaining hydrogeological parameters, which includes using ground penetrating radar to detect the area to be measured, and obtaining the volume water content and porosity of the unsaturated zone of the area to be tested; dividing the area to be tested into Several sampling areas, soil sampling in each sampling area to obtain columnar soil samples; the columnar soil samples were placed in the test cylinder for infiltration tests at different water temperatures to obtain the test permeability coefficient; according to the porosity of the unsaturated zone obtained by the Kozeny-Carman formula Estimated permeability coefficient, if the experimental permeability coefficient / estimated permeability coefficient = 0.9 ~ 1.1, the experimental permeability coefficient is adopted, otherwise, the experimental permeability coefficient in this test is discarded. The problem of low accuracy of the method for obtaining hydrogeological parameters in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of engineering geological survey, in particular to a test method for obtaining hydrogeological parameters. Background technique [0002] In nature, the phenomenon of irregular change and movement of groundwater is called hydrogeology. The hydrogeological conditions are relatively complex. Many engineering projects do not thoroughly study the hydrogeological conditions of the area during the survey process, and in the subsequent design stage The hydrogeological problems are ignored, resulting in frequent occurrence of a series of geotechnical hazards caused by groundwater, which not only greatly damages the reputation of the survey company, but also brings great economic losses to the society. Therefore, in the actual exploration process, it is of great practical significance to strengthen the research on hydrogeological problems. [0003] In the prior art, the hydrogeological parameters are usually obtained...
