Abstract

The invention discloses a vibration-control testing system of an unsaturated soil column. The vibration-control testing system comprises a seepage-flow and pollutant injection mechanism, an unsaturated soil column mechanism, a vibrating mechanism, a liquid discharging pipe, a confining-pressure applying and measuring device, a data acquisition system, an acceleration and excitation generating and recording device, a pressure chamber mechanism and a computer and the like. The vibration-control testing system disclosed by the invention has the advantages that a fixed-free type system is used for applying axial excitation and torsional excitation on the soil column, so that the defect that the existing conventional seepage-flow testing equipment can not consider the vibrational excitation and the saturability is overcome, the test for the transfer characteristic of seepage flow and pollutants under different vibrational excitation and soil-column saturability can be carried out, the confining pressure can be adjusted, and the vibration attenuating frequency and the soil-column deformation and the like can be accurately controlled and measured.

Description

technical field [0001] The invention relates to a vibration control unsaturated soil column test system in the field of seepage, which is used for measuring seepage and pollutant migration characteristics in unsaturated soil under the coupling action of vibration excitation, saturation degree and confining pressure. Background technique [0002] The propagation of seismic waves causes water level oscillations in the surrounding well-aquifer system, which in turn has a serious impact on seepage and pollutant migration in the surface unsaturated soil and underground aquifers. However, most of the existing indoor seepage tests are carried out under the condition of no vibration, ignoring the influence of vibration excitation. Secondly, a large amount of waste generated in daily life and production all over the world is dumped or landfilled in unsaturated soil layers. Pollutants in waste migrate and diffuse in unsaturated soil with gas, water flow and fine particles, which have ...
