  1. In this article, according to heat conduction theory, elastic creep theory and finite element theory, the temperature field and creep stress field in the arch dam during construction and operation are simulated and analyzed by means of three dimensional finite element relocating mesh method, and the distribution law of the temperature field and creep stress field in the arch dam during construction and operation are systematically studied, and according to the construction process of concrete arch dam, the effect of lamination placement, construction interval, elastic modulus change, thermal insulation change, surrounding temperature change, concrete creep and autogenous volume change on thermal stress in the arch dam are also considered

    論文根據熱傳導理論、彈性徐變理論及有限元理論，用三維有限元浮動網格法對拱壩施工期和運行期溫度場、徐變應力場進行了全過程模擬分析，較為系統的研究了混凝土拱壩施工期和運行期溫度場、徐變應力場的分佈規律，在分析中按照混凝土拱壩施工過程，考慮了混凝土分層澆築、施工間隙時間、彈模變化、絕熱溫升過程、環境溫度的變化、混凝土徐變、自生體積變形等因素對壩體溫度應力的影響。
  2. Based on the arch - cantilever method, the stability of arch ring and cantilever beam against elastic buckling in arch dams are analyzed with the theory of elastic stability, and the conclusion is drawn that the stability of arch dam against elastic buckling is governed by the top arch ring

    按照拱梁分載法的思想，用彈性穩定理論分別對拱壩的拱圈和懸臂梁的抗屈曲穩定性進行了分析，得出拱壩的抗屈曲穩定性由壩頂拱圈控制的結論。
