Back analysis of calculation parameters for Dashiban landslide at Three-Gorges Reservoir on Yangtze River;

The paper discusses the design method in the light of the structural characteristics,arrangement regulations,selection of calculation model as well as the principle of calculation,expounds further the structural characteristics and the selection of the calculation of typical control parameters and puts forward some suggestions for structural arrangement and calculation parameter selection.

According to the model founded, the corresponding calculation parameters are determined.

The yield conditions and calculation parameters of compressive strain hardening soils, and of dilative strain hardening soils are obtained through tests whose rationality is approved by the computed examples.

According to the author\'s experience,this paper presents some attention issues in the process of the design of retaining walls,including selection of the type of the retaining walls,calculation parameters,as well as retaining wall construction and use of uncertainties to give a reference to same designer.

This paper gives some kinds of view how to choose subsoil models correctly and how to determinate computation parameters for subsoil models.

Using the phase diagram of Fe-i system the author has calculated ATi and set up a set of new calculating parameter.
