一、绪言弹性地基上筏基和板基的性状已由科研工作者如:Borowicka(1936),Schultze(1961)和Brown(1969)进行了研究。对于文克尔型地基上,不同类型筏基的大量研究工作已由Allen和Severn(1960,61,63)作了报导。虽然,这些研究对这样一个特殊问题土-结构相互作用的性质提出了大量的见解,但这项工作与实际应用还相差甚远。很清楚,在实际应用中,还没有一个精确适用的方法可供使用。文克尔模型仅仅提供 I. INTRODUCTION The properties of sulfhydryl and plate bases on elastic foundations have been studied by scientific researchers such as Borowicka (1936), Schultze (1961), and Brown (1969). A large amount of research on different types of sulfhydryl groups has been reported by Allen and Severn (1960, 61, 63) for the Winkler type foundation. Although these studies have provided a lot of insights into the nature of soil-structure interactions for such a special problem, this work is still far from practical application. It is clear that in practical applications, there is no precise and applicable method available. The Winkler model only provides
