無粘結筋的極限應力增量一直是無粘結預應力混凝土結構理論中熱點問題，而從目前各國的設計依據及研究現狀來看，還沒有合理考慮多跨連續結構的無粘結筋極限應力隨荷載工況變化的情況。The research results show that aggregate gradation and the nominal maximum aggregate size evidently influence the shear resistance of asphalt mixture ; aggregate flakiness content influences the shear resistance of asphalt mixture, and with the increase of aggregate flakiness content the shear resistance of asphalt mixture decreases ; asphalt binder properties, especially penetration, softening point and viscosity influence the shear resistance of asphalt mixture, and the latter increases with the decrease of penetration and the increase of softening point and viscosity ; asphalt content influences shear resistance of asphalt mixture, and with the increase of binder / aggregate ratio the shear resistance of asphalt mixture decreases ; air void influences shear resistance of asphalt mixture, and usually with the increase of air void the shear resistance of asphalt mixture decreases ; homogeneity does not have a direct and obvious relationship with absolute value of shear resistance of asphalt mixture, but does with variation of shear resistance of asphalt mixture
研究結果表明：集料級配和公稱最大集料粒徑對瀝青混合料抗剪強度有顯著的影響；瀝青混合料抗剪強度受其集料中針片狀含量的影響較大，集料中針片狀含量增大，瀝青混合料抗剪強度減小；結合料的性質，特別是針入度、軟化點和粘度對瀝青混合料抗剪強度有較大的影響，隨著針入度減小，軟化點和粘度增大，瀝青混合料抗剪強度增大；含油量對瀝青混合料抗剪強度有較大影響，隨著油石比的增大，瀝青混合料抗剪強度減小；瀝青混合料抗剪強度受其空隙率的影響較大，一般隨著空隙率的增大，其抗剪強度減小；瀝青混合料均勻性與瀝青混合料抗剪強度絕對數值間沒有明顯的關聯，而與數值間的變異性有著很好的相關性。Researching on the technology if reverse order is to study strains if pits, structural systems if basement, environmental surwey and underpinnings. on account of emphasizing developing methods if checking strength if pick - ets, modemizing machenes of excavation and studying methods of underpinning is put forward and is a way if controlling the quality of pickets in sites, which leads an active effect ; synthetic application if rankintheory, spatial and time effect theory to excavation tl aanalyze the state of soil force and strain is brought forward and the time effect should be considered in the zone of clay, the formation and development of soil plasticity are analyzed and the most dangerous zone to decide how to excavate and where to begin is found ; analyzing the cause of picket settlement during reverse order and the differential settlement and discussing hlw to solute it. duringh the temporary survey and the environmental warship, bringing rorward the theory of environmental vibration and analyzing the state of soil force and probability of losing stabilization of soil under the effect of environmental vibration ; analyzing the state offeree in underground concrete wall by the method of mathematics and pointing out the place of the maximum force and deformation. based on systematic illustrating the reverse order, problems about application and development of reverse order and suggestions also are expressed
