Abstract:  Owing to its small elastic modulus and the better surrounding deformation co-ordination, the low elastic modulus cutoff wall has been applied in a number of water conservancy projects. With the more complex working conditions and more adaptive evaluation factors, there is currently no a full-mature evaluation method. Thus, from the hydraulic characteristics an adaptability evaluation system of low elastic modulus concrete cutoff wall was established, and, an example was analyzed using multi-level fuzzy comprehensive evaluation model. The results indicated that this is an adaptive and effective evaluation system, its analytic results coincide with engineering practice. the method provides a means of adaptation evaluation for the future water sector.
