試驗結果表明：與性能穩定之後相比，在混凝土中摻入鋼纖維對它的早期劈裂抗拉強度和抗折強度有尤為顯著的提高作用；對各齡期的受壓彈性模量影響不大，而對提高抗折彈性模量有一定的效果；與素混凝土試件相同，在早期（強度達到28天強度的85前）對鋼纖維混凝土試件施加荷載會對它的各種強度產生一定的不利影響，但是摻入鋼纖維可以減輕這種不利影響，尤其對劈裂抗拉強度和抗折強度作用突出，並且含纖率越高，效果越明顯。Through the research and analysis on the three aspects concerning the base interface of the pavement panel, crack accumulation, expansion in the pavement panel and interaction between spring plates on the road surface as well as its damage on the road fatigue, it is first brought forth that the process of fissures and breakage in the cement concrete pavement can be divided into three stages, i. e. stage of initial crack formation and damage in the bottom of the pavement slab, stage of accumulation, intensifying & expansion in ruptures from load during the time of use and stage of fissures & breakage in the pavement
通過對路面板底界面開裂、路面板中裂縫積聚、擴展和路面表面車板相互作用及其對路面疲勞破壞的影響等三個層面的研究和分析，首次提出水泥混凝土路面的開裂和破壞過程可以分為三個階段，即路面板底初始損傷西南交通大學博士研究生學位論文第11頁和早期裂縫的形成階段、使用期間荷載作用對路面造成的開裂損傷累計、加劇和裂縫擴展階段以及路面斷裂破壞階段。By the observation and analysis to the bearing function and break appearance of the rc beams with different forms in the experiment, and with theories of rc beams and strengthening by gluing steels, the most emphasis is placed on the three problems such as the capability of bearing bending, the classification and mechanism of the premature failure, and the rigidity and deflection under short - dated loading
通過對試驗中各試件梁的受力性能及破壞形態的觀察和分析，並結合鋼筋混凝土梁和粘鋼加固的有關理論，全文重點討論了三個方面問題：即粘鋼加固梁的抗彎承載力，早期破壞的分類和破壞機理，短期荷載作用下的剛度和撓度。Both embedded and non - embedded reports are accessed through the reportdocument object model : the embedded report is accessed through its early - binding report wrapper class that inherits from reportdocument, and the non - embedded report is accessed by its late - binding reportdocument class, which loads the report into the reportdocument instance at runtime
嵌入式報表和非嵌入式報表均通過reportdocument對象模型訪問：嵌入式報表通過其早期綁定報表包裝類（繼承自reportdocument ）訪問；而非嵌入式報表通過其晚期綁定reportdocument類訪問（該類在運行時將報表加載到reportdocument實例中） 。In this study, a 1. 7kb kpni fragment and a lacz gene expression cassette carrying the e. coli lacz gene under the control of sv40 promoter were inserted into the transfer vector pbdtk - uni ( a 277bp acci - accl fragment in the tk gene was deleted ). the new transfer vector was called puni - lacz. the transfer vector puni - lacz and purified genomic dna of strain bartha - k61 were used to cotransfect vero cells using lipofectin transfection procedure
本研究以呈ge ~ -表型的經典弱毒疫苗bartha - k61株為親本株，在通用prv轉移載體pbdtk - uni的基礎上，在其多克隆位點中插入由sv40早期啟動子控制下的lacz基因表達盒，同時將下游同源臂增加了一個1 . 7kb的kpni片段，使上下游同源臂的長度都超過了1kb ，構建了一個新的轉移載體puni - lacz 。All concrete structures are exposed to volume changes caused by hydration reactions in the early age. if the volume changes are restrained, stresses is generated which will cause cracking when it overcomes the tensile strength. as the mechanical properties of early age concrete vary with time, especially the creep degree depends on the time elapsed and the time at loading, to calculate the stress of concrete structure is a complex nonlinear problem. the finite element method ( fem ) can take account of the evolution of the stiffness properties, the development of thermal strain, creep, shrinkage and so on. in this paper, a general approach for numerically simulating this type of behaviour is presented firstly. then, how to solve this problem is introduced by the general finite element software ansys using the initial stress method. finally, a detailed description of an example calculation that demonstrates the potential of the numerical simulation strategy follows
早期混凝土由於水化反應都會產生體積變化.如果體積變形受到約束就會產生應力，一旦超過混凝土的抗拉強度就會產生裂縫.由於早期混凝土的力學性能是隨時間變化的，特別是徐變，它不僅與加載時間有關而且同時隨齡期而變化，因此計算早期混凝土結構應力是較為復雜的問題.有限單元法不僅可以考慮混凝土剛度的變化，而且可以考慮溫度、徐變、收縮等因素.本文利用初應力法對通用有限元軟體ansys進行了二次開發，通過工程實例計算了高層建築地下室側墻早期混凝土應力的變化過程，並提出了相應的抗裂措施Through studying the designed road surface curve and sink value, bottom stress and other aspects due to overloading, the paper found the effect of overloading to the road surface, and brought forward several reasonable suggestionsas follows : to optimize the road surface design, guarantee the compress degree of road surface, and to strengthen the management of overloading vehicles, etc
通過汽車超載對路面設計彎沉值、層底拉應力及其他方面的分析，論述了超載車輛對瀝青路面的影響及路面早期破壞的成因，提出在路面設計中應注意採用優化路面設計；在施工中應保證路面的壓實度，並應加大對超載車輛的治理力度。From the experiments, the number and width of fracture are obviously decreased, and pasting cfrp laminates play important role in improving rc construction durability ; with anchoring, premature is prevented and the ultimate shear capacity is increased ; taking properly anchoring measure, the ultimate shear capacity of rc t - section beams of initial loads is higher than that of no initial loads ; under non - anchoring case, because the rehabilitation of rc t - section beams with cfrp laminates are destroyed suddenly, the reinforcement effect maybe decrease
試驗結果表明，粘貼碳纖維布顯著減小了鋼筋混凝土t梁的裂縫數量和寬度，抑制了裂縫的開展，對提高普通鋼筋混凝土構件耐久性有重要作用；採用適當的錨固措施可以有效防止構件發生早期破壞，提高構件的極限抗剪能力；對于有錨固的粘貼方式，有預加載的t梁抗剪極限承載力明顯高於無預加載的t梁。試驗還表明，在無錨固的情況下，用碳纖維布作抗剪加固后的t梁破壞較突然，有可能使梁的加固效果出現負效應。In formerly static strength tests, no attention was paid to the process of test load. according to their experiences, experimenters adjusted pressure in actuator only by hand to control the test load value and the load value was read from instruments
早期的靜力試驗對加載過程沒有嚴格的要求，所以當時的液壓加載方式由試驗人員直接調整供油壓力，改變液壓缸內的油壓，控制活塞桿輸出的集中力載荷。分享友人
