【摘要】 目前承台设计可概括为两类,一类是将承台作为受弯构件,按“梁式体系”设计模式进行受弯、受冲切、受剪切承载力计算;另一类建议按“撑系杆体系”进行分析和设计。比较国内外各规范介绍的承台设计方法和研究成果,探讨了桩承台设计模式的运用和选择。并用例题对这两种设计模式做了对比分析。更多还原

【Abstract】 Recently pile cap calculation is divided into two categories:(1) Taking pile cap as a flexural resistance structural element, the capacity of flexural,the shear and punch resistance concerning pile caps are calculated respectively according to "Beam System" mode;(2) Pile caps are analyzed and designed according to "Strut-Tie System".The calculation methods introduced in each code and research fruits are compared;the application and the selection of pile caps calculation mode are explored;and the comparative analysis concerning these two calculation modes is made through using examples.更多还原
