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 *** 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 ***,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 *** study finds other advantages of the method like high efficiency in operation,flexibility in stratified test,as well as ***,the technology is of significant practical value and application prospect.

Acta Seismologica Sinica(English Edition) 1999年第3期12卷 365-367页

The permeation parameters have been calculated by forefathers on the basis of permeation theory by means of the slug test (Yin, Zheng, 1992) and the restoration curves of well level. We are interested in oscillation of the well level when we make slug test. Both the permeation parameters and frequency parameters, i.e., natural period and damping coefficients of well aquifer, have been calculated on the basis of vibration theory by means of the oscillation curves. Not only this has given a new method, but also the different response of well level to seismic waves has been explained by it in theory.

On-site tests to estimate aquifer permeability of drainage area of south caisson anchorage construction of Taizhou Bridge

Engineering Sciences 2011年第2期9卷 20-25页

作者： Feng Zhaoxiang Zhao Yanrong Jiangsu Provincial Yangtze River Highway Bridge Construction Commanding Department （JPCD） Taizhou Jiangsu 225321 China School of Earth Sciences and Engineering Hohai University Nanjing 210098 China

During the construction of the south caisson anchorage of Taizhou Bridge, the drainage area is located in the lower reaches of the Yangtze River and the permeability of stratums there is considerable. In order to maintain progress and guarantee safety during the sinking of the caisson, water should be drained in the initial period. Subsequently, detailed information about the aquifer permeability is required to make sure that the drainage will proceed successfully, which consequently necessitates the on-site estimation of the aquifer permeability in the drainage area. Therefore, the traditional pumping test and slug test are implemented respectively on site. The comparison of computational results of these two tests indicates that they are consistent overall. Notwithstanding, as slug test can be conducted with portable facilities in a short time and the manipulation is easy and few people need to be involved, the advantages of slug test is conspicuous compared with the traditional pumping test. It could be speculated that slug test will gain a prevalent application in the measurement of aquifer permeability in the future.
