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。 -
Abstract : the cause of underwater concrete reinforcing cage up - floating accident is improper operation, such as loose - placement of reinforcing cage, fast - drawing of conduct pipe, improper embedded depth of conduct pipe ; and the poor quality of concrete, for example, the slump, sand percentage, adhesiveness and initial setting time don " t meet requirement
文摘:水下混凝土澆注鋼筋籠上浮事故的原因是操作不當，如鋼筋籠固定不牢、提升導管過猛、導管埋深不當等，以及混凝土品質差，如坍落度、含砂率、粘聚性、初凝時間等不合要求。 -

After analyzing in detail the technical difficulties of constructing wams and the requirements of power system operation and control to it, the paper points out that the construction of wams should complement the existing scada ( supervisory control and data acquisition ) under present economic level, and the principle should also be conformed to during the placement of pmus
分析了構建wams可能遇到的諸如通信、存儲、管理、應用等技術難點;探討了電力系統運行控制對wams的應用需求;得出了在當前經濟技術水平下，構建wams應該考慮與現有scada系統互為補充的結論。討論了在wams ， scada互補系統中的pmu配置以及數據處理方法。 -
