场地地震运动特征及其对工程设施的影响

THE BEHAVIOR OF GROUND MOVEMENT OF A SITE AS A WHOLE DURING EARTHQUAKES AND ITS POSSIBLE EFFECTS ON ENGINEERING CONSTRUCTIONS

  • 摘要: 本文试图指出地震工程中尚未得到重视和研究的一个重要方面——场地波动特性对工程设施震害的决定性作用,而这种波动特性又取决于地震区场地的地质地形条件。 文中列举了一些地面震害的特性类型,它们表明场地在地震中以特定的形式作整体波动,因而地面上的工程设施也就屈从于同样的形式而产生破坏。这种运动形式和特点并不能用现有的地面(质点)运动反应分析方法进行解释和概括。因此,文章从波动场的概念和有关理论对列举的一些场地运动特征进行了初步分析和研究,并对相应的抗震问题提出了新的见解。

     

    Abstract: This paper attempts to deal with an important aspect which so far has not been taken up seriously, i.e. the waving behavior of a site as a whole, during major earthquakes which have definite effects on damaging of engineering constructions, and in turn such waving behavior will depend upon the geological and topographic conditions of the site.In this paper, several types of patterns of damaging of ground surface have been given by actual examples. They show that each site sways as a whole in a definite manner during earthquakes, causing engineering constructions on ground to be damaged in the same manner. Such a ground movement can hardly be described by the existing methods of seismic respponse analysis for a mass point on ground. Thus the authors try to make a tentative study from the view point of waving of a site, so as to give some new idea regarding the anti-seismic problems to be discussed accordinly.
