三峡永久船闸直立坡锁口锚杆应力监测分析 - The staged excavation and retaining can also be stimulated in this model . an engineering case is , as an example , analyzed and the validity and reliability of the model is proved by comparing the predicted deflection with those field measured . the behaviors of soil naing , the character of soil deflection and bar stress are applied to examine and parametric studies are also carried out to investigate the influnences of retaining parameters
本文首先建立了二维分离式有限元模型,土体本构采用多种本构模型,如e - b 、 l - d模型等,钉土之间采用goodman单元模拟,分析中能够模拟基坑的开挖与支护的施工过程,通过工程实例的计算,验证了模型的正确性、可靠性,通过对多组算例的计算分析,研究了土钉支护的内力及变形特征、工作性状及影响因素。 - The optimal model of truss structure is established , in which the cross sectional areas of bar are taken as design variables , the structure weight is taken as objective function . in the process , the reliability of structural displacement and bar stress and the fundamental frequency are taken as constraint functions . from the engineering practice , all the reliability constraints , which are implicit generally with the design variables , are equalized and transferred to the conventional explicit constraints
本文将主要考虑桁架结构的优化问题,首先建立数学模型,即以桁架的横截面积为设计变量、以重量最小为优化目标,位移、应力等可靠性及基频为约束条件;最后,从工程实际出发,对结构系统的可靠性隐形约束进行等价显化处理,使之转化为常规的横截面积优化问题。 - On the basic of former research men ' s experience , 18 experimental members ( including 9 simple beams and 9 restrained beams ) are designed and tested . in the experiment , phenomena are observed and record by taking photos in the whole process from the first crack appears to test members crash completely , experimental data is attained including load values of crack - appear load , critical load and terminal load , stress values of reinforcing steel bar stress , compressed concrete stress and beam flank stress and values of deflection etc . by analyzing the crack ' s appearing and developing form and stress values of concrete and steel bars , the crash modes of test beams are defined ; shearing force - deflection curves are contrasted and analyzed ; the effects on shear strength of the three factors as shear span ratio , concrete strength and restraining moment are also analyzed
借鉴已有试验的经验,本文设计和完成了对18根超高强混凝土无腹筋梁(包括9根简支梁和9根约束梁)在集中荷载下抗剪强度的试验,观察了试件从裂缝出现到完全破坏失去承载能力全过程的试验现象并通过拍照进行记录,获得了试件的斜裂缝出现荷载、临界斜裂缝荷载和极限荷载等荷载值和纵筋应变、混凝土受压应变和梁侧混凝土应变等应变值以及挠度值等。
