Abstract

To precisely reflect the anti-sliding stability of dam, a visualized software module was researched and developed to assess the deep-seated sliding stability of concrete gravity dam. Firstly, the stress distribution on the deep-seated sliding plane of the dam was numerically calculated. On this basis, by using the design method of the limit state of partial coefficient, the formula of shear strength was applied to each FEM element to define a new formula for the safety coefficient, thus an improved method of partial coefficient for the stability assessment was developed. In subsequence, the method was programmed by programming tool Delphi in association with AutoCAD. Since the advantage of FEM in calculating stress filed and considering dam foundation and body deformation is reflected in the method and the software module, and owing to the reliability degree taken into account as well, the obtained safety coefficient could well reflect the anti-sliding stability. Moreover, Ks expression in design specification is employed to make the method easy to use and popularize.
