本文緊密結合溪洛渡水電工程大跨度、高邊墻復雜地下廠房洞室群,施工開挖過程中和開挖后圍巖穩定性研究這一重大課題,在詳盡的野外地質調查工作和對大量基礎地質資料的整理與分析基礎上,以目前國際工程地質界公認的最新通用軟體flac ~ ( 3d ) 2 . 0版作為基本計算工具,從整個壩區地應力場的研究開始,通過動態數值模擬分析這一新的模擬思路,系統地研究了深切峽谷區地應力場多階段的特徵和演變規律,進而對左、右岸地下廠房洞室群開挖全過程中圍巖應力場、變形場和塑性破壞區的變化特徵,進行了全過程動態數值模擬研究,並詳細討論了圍巖質量、初始地應力場、施工開挖順序對大型地下洞室群圍巖穩定性的影響。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?應變曲線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射線衍射實驗,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凝膠和未水化水泥顆粒組成;在抗溶液侵蝕的實驗中,摻礦渣rpc的抗溶液侵蝕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的結構產生侵蝕作用,但是機理各有不同。The following two chapters make of the third part. chapter five analyses the failure factors of test model and identifies the valid scope of two - part wedge theory. chapter six extends the valid scope of two - part wedge theory, and puts forward integer slide theory, then uses the extended theory calculating a concrete project, seismic design suggestions are proposed finally
第三部分包括第五章和第六章,第五章對試驗模型的破壞影響因素進行數值分析,確定了「雙滑楔體」理論的適用范圍,並對各種破壞因素進行了分析;第六章拓廣「雙滑楔體」理論適用范圍,補充介紹了整體滑動理論,應用拓廣后的理論計算實際工程,為實際工程的基坑邊坡設計提供參考依據。( 6 ) conclusion was obtained by the analyzing the mechanics environment and the stability of the lanslide on the right bank after the dam built : the value of the rock mass stress increased and the tensile stress region obviously reduced, the direction of the principal stress was unchangeable the dam and the landslide were stable under the dangerous condition ( the reservoir and at the same time the earthquake was viii ), but when the water lever suddenly fell and did not think of other force, safe factor evidently reduced, the dam and the landslide will be destroyed under the most dangerous condition ( the water lever suddenly fell and at the same time the earthquake was vi ) ; the stability of the landslide will be destroyed by the horizontal thrust under the most dangerous condition or ; the physical and mechanical parameter will be reduced due to long period filter, the landslide will be destroyed too
( 6 )建壩工程荷載條件下河谷巖體力學環境分析及右岸古滑坡體的穩定問題分析得出:建壩后河谷的巖體應力量值明顯增高,同時左岸的張應力區的范圍及量值明顯減小,主應力的方向依然與模型的底邊界垂直;大壩建成后逐漸蓄水階段以及同時考慮本區最強地震力的作用等各種不同的工況條件時,滑坡體及壩體總體上仍處于穩定狀態;水位驟降時,在未考慮其他外力作用的情況時,滑體的安全系數將顯著降低。若考慮水位驟降及本區最大地震力的共同作用,壩體將在滑坡體下滑推力的作用下產生破壞;建壩后水平推力對右岸古滑坡體穩定性的影響分析可以看出,在最危險的工況條件下,壩體及滑坡體也將處于臨界狀態;在長期滲透變形的作用下,由於滑帶的物理力學參數的降低而有可能導致壩體失穩破壞。The methods of shear strengthening of reinforced concrete beams with cfrp are described in this article. the ways of shear - destruction of the beams, the factors affecting shear resistance capacity, the developing of stress are also introduced

由於已有研究對后植鋼筋粘結錨固的失效形式、破壞機理未作出明確回答,對后植鋼筋粘結錨固性能的影響因素未進行系統研究,對后植鋼筋粘結錨固的長期有效性未予以試驗證實,不利於植筋技術這種新型結構加固技術的推廣應用,同時現有植筋錨固材料存在品種少、價格高、性能需要進一步改進和提高等局限性,已成為植筋技術發展的瓶頸,制約了植筋技術的進一步應用和發展,因此開發價格合理、性能優良的新型高性能無機質類錨固材料就顯得尤為重要和迫切。Shocks like the tuesday ' s after - hours surge will have a more disturbing impact, as buyers suddenly slash their spending, as happened in america after hurricane katrina disrupted supplies

本文共進行了24根試件的試驗研究,得出了預應力混凝土芯棒能較大地提高構件抗裂承載力,在荷載小於預應力混凝土芯棒的開裂荷載時有較好的抗裂效果,能較大地減小裂縫間距和裂縫寬度,但是當荷載較大預應力混凝土芯棒開裂時預應力混凝土芯棒的抗裂效果不是很好,若將普通鋼筋和預應力混凝土芯棒一起使用時則有很好的抗裂效果。本文分析了預應力混凝土芯棒在軸拉試件中的粘結機理和破壞機理,根據預應力混凝土芯棒本身的特點,提出了預應力混凝土芯棒與后澆混凝土之間的粘結模型。然後本文詳細介紹了經典的裂縫分析理論粘結滑移理論、無滑移理論、綜合理論和數理統計方法,各理論有著各自不同的理論基礎,認為影響裂縫寬度的主要影響因素也各不相同。Fatigue test indicates that strain multiplier have not been damaged for fatigue in the service life of fatigue life gage, fatigue response of fatigue life gage can be derived from the strain amplitude equal to specimen strain multiplied by amplification coefficient of strain multiplier
