A Field test Data Research Based on A New Hydraulic Parameters Quick test Technology

The hydraulic parameter quick test system in accordance with the oscillation principle can overcome the shortcomings of traditional methods in determining hydraulic parameters which, besides having complex hydrogeological restrictions and needing complex equipment in the field, are often both time and energy consuming, and high cost. Based on the hydrogeological conditions in the north anchorage of Taizhou Yangtze River Highway Bridge, a quick hierarchical test is carried out for different depths of single-hole drilling to verify the function of the system in this case. Meanwhile, with a purification of the raw data gathered in the test by wavelet denoising, the hydraulic parameters are worked out by adopting the Kipp model. A comparison between the Kipp model results and stratigraphic data as well as pumping test results justifies the reliability and accuracy of the new method. The study finds other advantages of the method like high efficiency in operation, flexibility in stratified test, as well as environmental-friendliness. Therefore, the technology is of significant practical value and application prospect.
