Research On The Experimentation Of Mositure Movement In Unsaturate Loess Soil Considering Freezing

Research on the experimentation of moisture movement in unsaturate loess soil Considering Freezing under the different water content,soil density and freezing time.It is indicated that the give length soil sample freezed under the given freeze grads.It is also included the most water content in the freezing surface,the more water content in freezing area and the less water content in unfreezing area under the given freeze grads. The water concent of the freezing surface and the area of the freezing area is increased with dry density,water content,freezing time,freezing grads.The freezing grads influenced the place of the freezing surface at the most.The dry density have some influence,but the wate content and the freezing time have little influence.Research on the experimentation of the different dry density,water content soil sample install with grid.The result showed that whether or not install the grid,The dry density,water content,freezing time isn't influence the regular of the moisture movement.Compared the mixture moisture movement with the install grads moisture movement,the result of the the experimentation is almost sameness in lower water content.The result indicated that vapourous water movement is obvious in lower water content.The freezing surface and the unfreezing area water content have significant difference in middle water content,this result indicated that the mixture moisture movement is obvious.In highe water content,the the water content of the freezing surface and the unfreezing area has much difference,it shows the moisture movement is main with liquid water.Analyse the data of the experimentation,get the formula of the water quantity which moisture movement the freezing area under the some dry density,water content,freezing time,freezing.
