The Research Of Appraising On The Effect Of Soft-soil Reinforcement By Vibration And Wave Compositive Method

The project of soft-soil reinforcement could be seen everywhere,which direct concen the after construction and indirect concern the peoples'life and property. So, It is very important to estimate the effect of soft-soil reinforcement. In this paper,its mostly study is how to appraise the effect of soft-soil reinforcement.Firstly, some appraising method of soft-soil reinforcement are discussed and analysed. and,the disadvantage of these method are pointed out.Secondly, basing on the vibration theory ,some method which was used to test the value of bearing capacity are introduced.Such as the method of frequency ,the method of frequency-wave velocity,the method of additive mass.Basing on the method of frequency and pauw theory, A meliorative method of dynamic parameters is put forward. adoptting different area of boards and using linear regression, a credible rigidity coefficient of soil foundation could be get.Thirdly, Adoptting the method of numerical analysis, through the dynamic analysis of the soil foundation, the curve of displacement-time and the value of frequency would be got. Then, though the theorical analysis, the influencing depth could be got. Comparing the pauw theory and numerical analysis, the value of bearing capacity is almost equivalent.Fourthly, The shear wave and rayleigh wave are introduced. The relation of wave...
