In analytical technique to clear up the problem of the slope, there is a thing to follow in transformation that I evaluate the stability of the slope. However, the supposition of the collapse form is necessary in the conventional analytical technique, and expression of detailed collapse mechanism is difficult, and there is a problem that there is influence of the initial stress, and there is danger to lose the reliability of the solution in the slope having the uncertain information of nature slopes. Therefore, in this study, I paid my attention to RPFEM as effective technique for these problems and developed stability evaluation technique and the transformation analytical technique how I used RPFEM for for the purpose of I was highly precise, and solving the problem of the slope. In the development of the transformation analytical technique, I enabled in particular a transformation calculation for the dynamic load by performing formulation corresponding to the issue of stress boundary value. In addition, I carried out comparison with the theory solution as inspection of the validity of this analytical technique. Furthermore, in the ground having the slope, I clarified the utility of this analytical technique by carrying out stability evaluation and transformation analysis
