  边缘应力
     The designing material and the construction material is also analysed. And the stress distribution is calulated through SAP84 Finite Element Analysis System. The major reason of the accident is the lack of knowledge of computation theory and joint structures,so there is large stress in the joint zones.

  large stress
We suggest that the concentration of large stress drop values at 10-36km depth may be related to the large stress/strain associvated with a brittle, competent intrusive body of mafic nature.
      
Looking at the average stress field we see a large stress concentration left at the edge of the large events, out of which the future events emerge.
      
However, large events in the nonconservative uniform automaton and in the fractal systems produce large stress perturbations that move the system out of the critical state.
      
Six events with large stress drop are located within a previously suggested asperity, and seven more suggest a boundary zone at the intersection of the Petatlan and Zihuatanejo aftershock rupture volumes.
      
The wave may accumulate at the focusing point and give rise to very large stress magnitudes, even though the initial stresses may be relatively small.

This paper recommands the design method of Dandong Shahe large bridge and the calculation results. The dynamic analyses of the large-spanned arch bridge and the related problems of the earthquake-proof construction design is explicated.We have the following views:1. Because of the curvature of the arch axis and the effect of the elastic compression, the effect of the vibration couplings of the orthogonal directions in the arch plane is very obvious. 2.When the earthquake sets on the arch plane,there will be considerable strain on the lower edges of the arch springings. This is in agreement with the damage phenomenon of the arch axis. Large stress and strain may occur from L/4 to the arch crown. 3. When the earthquake acts outside the arch plane, a very large horizontal displacement and torsional moment will occur in tee arch rib. In Tongshan earthquake two lower bearing tyqe arch bridges collapsed. This was the consequence of the horizontal earthquake action. 4. The effect of the vertical earthquake component is quite big. It should not be neglected in the earthquake-proof construction design. 5. The maximum type parameters and coefficients may occur in the higher-order vibration type, therefore, if we merely make computations for the earthquake-proof construction design of the large-spanned arch bridge of the first vibration type, it may not be safe and sound. 6. There is the apparent effect of the earthquake hypogene to the arch bridge earthquake by the frequency spectrum of the earthquake wave. Therefore, we consider that it is apt to proceed the overall computations for the aseisma tic constructions by means of the dynamic analysis in dealing with the large-spanned arch bridge.

本文介绍丹东市沙河口大桥抗震设计方法及计算结果,论述大跨拱桥动力分析和抗震设计中的有关问题。得到以下看法:1.由于拱轴线曲率及弹性压缩的影响,拱平面内两个正交方向上的振动耦联效应十分明显;2.在拱平面内地震作用时,拱脚下缘会出现较大的拉应力;L/4至拱顶会出现较大的压应力。这与常见拱桥震害现象是一致的;3.拱平面外地震作用时,拱肋会发生很大的横向位移和扭矩。唐山地震中两座下承式拱桥坠落,是横向地震作用引起的后果;4.竖向地震分量对拱桥的影响很大,抗震设计时不容忽略;5.最大振型参与系数可能出现在较高阶振型,所以,只计算第一振型的大跨拱桥抗震设计方法可能是不安全的;6.地震波的频谱特性对拱桥地震内力和位移有明显的影响。因此认为,大跨拱桥宜用动力分析法进行全面的抗震计算。

After the experimental and calculative results are compared, It is suggest that the spherical specimen is adopted as standrad specimen. Its advantages are:...

This paper deals with contact stress for specimens of different shapes (rectangle, trapezoid, sphere) using the three- dimensional photoelastic method. The specimens are recommended according to the temporary rule of the testing method for the contact fatigue testing machine(JPM— 1 and JP—BD) . The distributive case of stresses can be obtained. After the experimental and calculative results are compared, It is suggest that the spherical specimen is adopted as standrad specimen. Its advantages are: (1) The request isn't severe to experimental condition and the comparability of experimental results is good. (2) The spherial specimen is typical because it is similar to the shape of most parts that is subjected to fatigue failure in engineeing practice (3) A small force exerted on the specimen can produce a comparatively larger stress . So the useful life of loading axis can be prolongeol

本文对JPM—1型和JP—BD型接触疲劳试验机试验方法暂行规定中所推荐的几种不同形状(凸台形、梯形、园弧形)的试样,进行了三维光弹接触应力分析,定量地得到了应力分布情况。在对实验和计算结果进行了比较之后,建议采用园弧形试样为标准试样。其优点是:(1)对实验条件的要求比较宽,试验结果可比性好;(2)试样形状接近工程实际中多数产生疲劳破坏的零件,因而具有典型性;(3)加比较小的载荷就可在试样内产生较大的应力,因而可以延长接触疲劳试验机加力轴的使用寿命。
