| 摘 要： | 针对龙滩碾压混凝土重力坝的特点，采用多种非线性分析方法研究坝体的应力和承载能力。考虑碾压混凝土损伤软化和扩容等实际性质，提出用稳定性分析方法研究重力坝的承载能力，给出失稳的判别准则，使重力坝承载能力的分析建立在一个严谨的力学基础之上。最后对于采用多种理论得到的研究成果进行了分析和比较。

| Abstract: | In view of the characteristics of Longtan RCC gravity dam, multiple non linear analysis methods are adopted to study the stress and bearing capacity of the dam. Considering the actual natures of the dam such as softening and expansion, stability analysis method is recommended for studying the bearing capacity of the gravity dam and an instability criterion is given as the mechanics base of the analysis. At last, the study results obtained through various theories are analyzed and compared in this paper. |
