  1. With the very low water to cement ratio, rpc has ultra - high strength high ductility and low permeability. in this paper, the compressive strength of rpc can reach to a high point with the number approximately 135mpa. as illustrated from the study results, we can approve some fundamental conclusions : there are big effects on rpc with deferent kinds and properties of raw materials and deferent curing conditions ; stress - strain curve shows the process of destroy with rpc samples ; x - ray diffraction analysis indicates that heat treatment at temperatures 90 accelerate the hydration of rpc sharply, therefore, mechanical and microstructural properties of rpc are highly dependent on heat treatment ; it is believed that rpc materials have excellent resistance to chloride permeability ; during the heat treatment, the shrinkage of rpc developed quickly because of chemical reactions ; the rpc with slag mostly has the advantage of rpc without slag about resistance to solutions corrosion

    研究結果表明:通過對rpc各組分摻量變化的研究,可以找到rpc的最優配合比;試件成型后的熱養護制度對rpc的性能影響巨大; rpc的抗壓應力?應變可以反映出試件受破壞時微裂紋的擴展情況,剛纖維的摻入可以大幅改善rpc的韌性; rpc在成型后存在較大的收縮,而其中的化學收縮要遠遠大於乾燥收縮; rpc具有很強的抗氯離子滲透性能,漿體的密實度很高;通過x射衍射實驗,可以發現rpc的膠凝體中ch晶體已經幾乎不存在,膠凝體主要由c - s - h凝膠和未泥顆粒組成;在抗溶液侵的實驗中,摻礦渣rpc的抗溶液侵性能在絕大多數情況下要好於不摻礦渣試件,酸、堿溶液和浙江工業大學碩士學位論文摘要一些鹽溶液都會對rpc的結構產生侵作用,但是機理各有不同。
  2. With metal fatigue in material mechanics, this paper deduces the limestone fatigue curve of longmen grottoes by means of marble s one within the error permission. by the experiment elects the crucial factors of current vibration environment in longmen grottoes, the author contrasts the result of the experiment with its fatigue curve referred above and analyses the fatigue effect of longmen grottoes. finally, it is pointed out that after longmen grottoes have being suffered weathering and water - erosion more than 1500 years, the vibration environment is becoming an crucial factor leads to fatigue effect, especially in those weak surface carvings just like the crossings of several rifts, serious weathering places, etc

    借鑒材料力學中金屬疲勞破壞的研究手段,在誤差允許范圍內用大理巖疲勞推導出門石窟石灰巖疲勞。通過對石窟實際振動環境中典型要素的抽取和振動試驗,將試驗結果與疲勞進行對比,分析了門石窟的疲勞破壞效應。文章指出,在經歷了1500多年的風化和流后,振動環境已成為導致門石窟某些薄弱點如多條裂隙交叉點嚴重風化酥解的壁面雕刻品等產生疲勞破壞的重要誘發因素。
