[提要] 規(guī)范JCJ 94-94及CECS 88:97為樁承臺合理設(shè)計提供了依據(jù)。作者在編制《鋼筋混凝土低樁承臺通用圖集》的過程中，發(fā)現(xiàn)對二樁承臺高度的合理確定需要進(jìn)一步探討。通過多份有關(guān)文獻(xiàn)及大量計算實例的對比分析，提出了比較實用的合理確定二樁承臺高度的方法。
[關(guān)鍵詞] 剪跨比 剪切系數(shù) 沖跨比 沖切系數(shù) 二樁承臺合理高度The rules of JGJ 94-94 and CECS 88:97 provide a basis for reasonable design of pile caps.But in course of compiling Common, Design, Atlas For Reinforced Con,crete Pile Caps, it is found that the reasonable height of two pile caps need to be discussed.Through comparison and analysis of relative references and calculation examples,this paper glves a simple method to establish the reasonable height of two pile caps.
Keywords: shear span ratio; shear coefficient; punching span ratio; punching coefficient; reasonable height; two pile caps
