  4. This paper, in allusion to damage of expansion joint of bridge, introduces a sort of new structure of jointless device - semi - integral abutment jointless bridge, and establishes model of general structure finite element of this bridge, and in details analyses its qualities of stress. the model considers the interaction of superstructure - substructure - soil. resistance of the soil behind abutment adopts still soil pressure and elastic resistance when the temperature rising, but active soil pressure when dropping. analysis of qualities stress of bridge includes of action of dead load, car load, temperature load of season character. taking an 100m length pc semi - integral abutment jointless bridge as instance, the paper establishes the model of plane frame by applying large common software - anasys, and analyses it by elastane and large deformation to imitate character of stress and deformation of general bridge. at the same time corresponding models of finite element of joint bridge and integral abutment bridge are established, and unique stress and performance of structure of semi - integral abutment jointless bridge are researched by comparing and analysing character of three different models under same loading, and controlling factor of design and constitution are generalized. in conclusion, for semi - integral abutment jointless bridge, on one hand shear, moment and deflection of the main beam and axis force of substructure are approximate with that of joint bridge, and integral stifmess of structure is increased and damage of expansion joint is eliminated, on the other hand there is axis force in main beam, shear and moment of substructure are bigger than that of joint bridge. in all this type of jointless bridge has rational stress and is worth of application and popularization

    半整體式橋臺無縫橋梁計算模型考慮了上部結構-下部結構-土的共同;臺後土抗升溫時採靜止土加彈性土抗,降溫時採主動土;分析橋梁受性能時考慮了結構自、車輛荷載和季節性溫變荷載的。以一座橋長100mpc半整體式橋臺無縫橋梁為實例,採大型通軟體ansys建立平面框架模型,進行彈性、大變形分析,模擬全橋受和變形特點;同時建立與此對應的有伸縫橋梁和整體式橋臺無縫橋梁有限元模型,通過三種橋型同步加載對比分析,研究半整體式橋臺無縫橋梁獨特的受特點和結構性能,總結其設計控制因素和構造要求。通過本文研究知:半整體式橋臺無縫橋梁主梁的剪、彎矩、撓度和下部結構的軸與梁式橋相近,結構整體剛度增大,併除去了伸縫病害;但主梁增加了軸,下部結構剪、彎矩較梁式橋大;綜合分析是一種受合理有實踐和推廣價值的橋型。
  5.

  8. Through analyzing the means of military financial mobilization, such as collecting taxes, issuing bonds, using foreign exchange reserve, mobilizing people to donate to government and limiting to pay internal saving deposits, the paper considered that issuing bonds at home was fundamental way to mobilize financial resources in wartime, and that using foreign exchange reserve, mobilizing people to 37 donate to government and increasing the proportion of national defense expenditure in the whole expenditure were important means that our government could select. in addition, the paper thought that there were great negative effects using the ways of adding to tax burden by increasing tax rate and setting new tax category and limiting to pay internal saving deposits to mobilize financial resources in wartime, so government would select them on condition that financial resources mobilized by other ways did n ' t supply enough financial resources that wars demanded

    本文通過對徵收賦稅、發行公債、動外匯儲備、動員社會捐贈以及延緩支付國內儲蓄等動員途徑進行研究分析,認為發行國內公債可以及時動員大量資金參戰,且負較小,是我國戰爭財動員的主要途徑;在不增加社會稅收負擔的情況下,通過其他財政支出而動員戰爭財的方法、以及動國家外匯儲備和動員社會捐贈是我國戰爭財動員可以選擇的要途徑;由於提高稅率和徵收戰爭稅以及延緩支付居民儲蓄的負面影響較大,因此應根據戰爭的實際需要慎使
