The Solidification Liquefied Soil The Solidification Liquefied Soil Mechanical Properties Research For Fiber Material

In Japan,from the urban construction site soil,in many cases are discarded as industrial waste to landfill,within a long period of time,waste have not been widely and effectively used.Therefore,how to use the construction of the soil has become a problem to be solved,for Japan the use of "flow of soil" method to solve the utilization problem,and Liquefied Soil Stabilization treatment is mainly applied to the backfill soil and the filling is not easy to be compacted.Because the traditional processing method flow defects in brittle in terms of use,the purpose of this study is to how to reduce Liquefied Soil Stabilization treatment is fragile,so that it can be used for building materials are more extensive and effective.In indoor and outdoor Liquefied Soil Stabilization treatment experiment.According to the result of experiment,the flow of a modified effect more obvious Liquefied Soil Stabilization treatment to add fiber materials,Liquefied Soil Stabilization treatment to be added Liquefied Soil Stabilization in the treatment,the newspaper(40g / m2)to carry on the cotton processing,stirring.According to the amount of different fiber materials,curing time,and the interior of the experimental samples compacted undrained triaxial compression tests of the three samples,the mechanical property test.Through the analysis of the indoor mechanical test data of different curing time,the content that convection fiber material processing effect of soil was brittle,add the amount is 100 kg/m3,the confining pressure is 98 kPa,the curing time is 56 days,the relationship between fiber increased,and with the increase of fiber materials,soil brittleness improvement effect is more obvious;the smaller type and amount of cement material brittleness effect on soil materials,which are considered as the main fiber materials play a role in improving soil fragility;indoor outdoor protection samples when compared to the maximum axial stress difference in gradually become larger.The outdoor samples,with the increase of curing time,reduce the ratio of / In the decrease,but in the 150 day of the time to reduce the ratio has become larger.After reaching the highest point of the mixture of fiber materials,its vulnerability has been improved.
