1. On this basis , regarding the rankine soil pressure theory as the prerequisite , the active earth pressure formula considering the deformation of braced structure has been set up . the calculation of active limit displacement in the formula has been researched , and proposes two methods ; all of which are applied to active soil pressure formula considering the deformation of braced structure . further , combine the project example , the active earth pressure formula considering the deformation of braced structure has been tested and confirmed its rationality
   本文介绍了基坑支护结构的形式、特点,以及目前工程中基坑的设计计算方法,分析了土压力的计算在基坑工程设计计算中的重要性;通过实测的基坑主动土压力与支护结构位移的分析得出基坑主动土压力与位移之间存在密切关系,在此基础上以朗肯土压力理论为前提建立了考虑基坑支护结构位移的主动区土压力公式;并对公式中的主动极限位移的计算做了研究,提出了主动极限位移的两种计算方法;把这两种方法都运用于考虑支护结构位移的主动土压力计算公式,进而结合工程实例,对考虑支护结构位移的主动土压力公式进行了验证,验证了公式的合理性。
2. It was shown that the measured active soil pressures were smaller than the theoretical values and diminished with time , the measured pore water pressure decreased with the time and increased with the depth of soil , the combinative effects of cap girder and supporting structure were obvious which diminished the displacement of foundation pits , and the measured axial force of the anchor and interior steel beam were far less than the design force , indicating that the design safety factor of the foundation pit was too large to be economical
   基坑工程实行信息化施工并获得了丰富的监测数据，通过对数据分析结果表明：实测主动土压力小于计算主动土压力，实测主动土压力随时间延长变小：土体中孔隙水压力随时间增长而减小，孔隙水压力随深度增加而呈非线性增加；基坑冠梁协同作用明显，冠梁减小了基坑变形；锚索轴力比较稳定，钢撑轴力变化相对较大，且二者轴力仍富余较大，该设计比较安全。
3. The rankine soil pressure theory is always accepted as the foundation of calculations of the soil pressure in practice . but as we know , the ignorance of the middle principal stress and the utility of mohr - coulomb strength criterion in the two - dimensional stress state make a blemish that the active soil pressure is bigger and the passive soil pressure is litter than the real
   朗肯土压力计算公式一直是工程实际土压力计算的理论基础，但是朗肯土压力计算公式在推导过程中忽略了中主应力的影响，仍然应用二维应力状态下的莫尔?库仑强度准则，致使计算出的主动土压力偏大而被动土压力偏小。
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
   半整体式桥台无缝桥梁计算模型考虑了上部结构-下部结构-土的共同作用；台后土抗力升温时采用静止土压力加弹性土抗力，降温时采用主动土压力；分析桥梁受力性能时考虑了结构自重、车辆荷载和季节性温变荷载的作用。以一座桥长100mpc半整体式桥台无缝桥梁为实例，采用大型通用软件ansys建立平面框架模型，进行弹性、大变形分析，模拟全桥受力和变形特点；同时建立与此对应的有伸缩缝桥梁和整体式桥台无缝桥梁有限元模型，通过三种桥型同步加载对比分析，研究半整体式桥台无缝桥梁独特的受力特点和结构性能，总结其设计控制因素和构造要求。通过本文研究知：半整体式桥台无缝桥梁主梁的剪力、弯矩、挠度和下部结构的轴力与梁式桥相近，结构整体刚度增大，并除去了伸缩缝病害；但主梁增加了轴力，下部结构剪力、弯矩较梁式桥大；综合分析是一种受力合理有实践和推广价值的桥型。
5. The conclusion is that it is more similar to practical soil pressure distribution if shear strength parameters are used which are obtained by the experiments that can simulate the actual process of active soil during excavation . so it is more reasonable to use shear strength parameters obtained by tri - axial experiments that can simulate the process of excavation in design of retaining structure
   本论文得出的结论是：用模拟基坑开挖实际应力路径的试验方法得出的抗剪强度指标计算基坑侧土压力分布，与实际情况更为接近，在基坑支护设计中，应该尽量使用模拟基坑开挖实际应力路径的三轴试验方法确定土体抗剪强度指标。
