摘要

基于混凝土重力坝深层滑动面上应力分布情况的数值计算成果,结合分项系数极限状态设计方法,研究了一种评估混凝土重力坝深层组合滑动稳定性的改进分项系数法。在此基础上,利用Delphi 编程工具,结合AutoCAD二次开发技术对该方法实现了程序化,得到了评估混凝土重力坝深层滑动稳定性的可视化软件模块。该方法和软件模块,充分利用了有限元数值模拟方法在计算应力场和考虑坝基及坝体变形影响等方面的优势,又结合了可靠度设计方法,得出的稳定安全系数能够较好地反映重力坝的抗滑稳定特性,且沿用了设计规范中的K_s表示方法,易于计算和普及。

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, K_s expression in design specification is employed to make the method easy to use and popularize.
