  1. According to the geological conditions of baise project, erosive bands and joint fissures, f6 fault and grout curtain are fully simulated to establish 3d numerical model of the dam and its foundation. 3d non - linear fem is used to analyze the stress and strain and to appraise the operation state of both the dam and it ' s foundation under different operation conditions. by overloading the upstream water level and reducing rock strength parameter, the dam foundation ' s degradation process is simulated and the damage pattern and paths are determined, and finally the safety factor is determined

    2 、根據百色的地形地質條件,充分模擬了蝕變帶、節理隙、 f6斷層、灌漿帷幕等,較為真實地建立了壩體與地基相互作用的整體三維值模型;採用有限元法對壩體及壩基在不同工況下的應力應變狀態開展分析,評價各工況下壩基的運行狀態;而後採用超載法和綜合法對大壩穩定性進行分析,模擬壩基的漸進性壞過程,從而得到壩基在超載和強度下降過程中的壞模式和壞發展路徑,最終確定壩基超載和綜合
  2. The paper is on how to set up lab platform of vapour spewing to uppercooling water surface to coagulate directly and to observe and analyse which vapour coagulate on the water surface, the results enable people to know the security system of nuclear power. the range of the pressure parameters of prz is from 0. 2mpa to 0. 6mpa, and the range of the initial temperature parameters of cmt is from 23. 5 to 78. 5, all of the testing points are 30 and there are fifty thousand testing data. many results of vapour spewing to uppercooling water surface vertically to coagulate can get. for example : coagulating can make the water of cmt surge forcefully when vapour spews to uppercooling water surface, too many vapour - bubbles come into being and strike the water of cmt owing to rupture continually, all these will strengthen the surge because of the vapour pressure of cmt

    實驗中prz飽和蒸汽壓力變化范圍為: 0 . 2mpa - 0 . 6mpa , cmt中水初始溫度變化范圍: 23 . 5 - 78 . 5 ,實驗中測試工況30個左右,實驗測試據50萬余個,得出了很多與非能動統相關的蒸汽垂直噴向過冷水表面凝結時的結論:蒸汽垂直噴入過冷水表面凝結時會造成cmt中液面的強烈波動和振蕩,產生大量蒸汽汽泡,汽泡不斷對cmt中液體帶來很大沖擊,勢必引起cmt中液體的振蕩,造成cmt汽空間汽壓不均勻,加強cmt液體的振蕩和波動。
  3. Abstract : based on soil plasticity and limit analysis theory, the second failure surface of backfill behind retaining wall with gentle back surface are studied from two view points of maximum active soil pressure and minimum resistive overturning safety factor, and it is further considered that the minimum resistive overturning safety factor is the best approach to studying the failure mechanism of backfill under complex back surface conditions of retaining structures

    文摘:基於土的塑性極限分析理論,從擋土墻最小抗傾覆和擋土墻背上的最大主動土壓力兩個角度,分別研究了坦墻後土體中第二面的位置,認為在復雜的擋土結構墻背條件下,用最小抗傾覆來研究擋土墻後土體的壞機制較為合理。
