The Model Testing Study On The Frozen Wall Forming Affected By Seepage Water In Saturated Sand

The study on a frozen wall forming affected by seepage water is not only an important and difficult problem , but also an urgent one to be solved in the Artifical Ground Freezing engineering. In this paper , a model testing system of frozen wall forming under the function of seepage water of which the process is simulated in saturated sand layer is established on basis of the foundamental principle of the theory of similitude . Based on the process and analysis of the data from orthogonal test, a series of the quadratic polynomial regression formula on the relations between the circle-crossing time or the differential coefficient of frozen wall and the four influencing factors have been obtained. The laws of the forzen wall forming affected by seepage water briefly concluded and analysed in this paper will be good for the design and implementation of the Artifical Ground Freezing project.
