pile foundation

Combined with practical engineering,the author poses concept and construction technique of column footing protection,introduces pile foundation structural design of rail pile,illustrates construction techniques of stressing pile by static force,connection between steel pile and pile foundation,and rotary jet grouting pile construction,which to popularize this kind of construction method.

通过工程实例,提出了柱基础保护的思路及施工工艺,介绍了钢管桩桩基结构设计,详细阐述了静力压桩、钢桩与柱基础连接、旋喷桩施工等施工工艺,以推广该施工方法。

Basing on the demonstration about the design of puncheon foundation,whether puncheon foundation can be inbuilt-end of frame bottom post is presented.

对短柱基础能否作为框架底层柱的嵌固端提出看法 ,旨在减少底层柱的计算长度 ,以满足底层的侧向刚度不小于相邻上一层侧向刚度的 70 % ,使结构计算简单化 ,避免繁琐的计算 ,供工程设计的同行参考。
