%X <span style=\"text-align:justify;white-space:normal;\">墩基础的设计方法在现行规范中没有明确的规定，造成了土木工程设计中的浪费或安全隐患。本文分析了墩基础在岩石和非岩石地基中的受力机理和破坏模式，认为不能简单地按墩基础墩径比确定其承载力计算方法，应根据墩端地基土的特性合理确定，并提出了墩基础必须满足的独立基础和桩基础的设计构造要求。<br />
</span><span style=\"font-size:12px;line-height:1.5;text-align:justify;white-space:normal;\">The design for the expanded-pier-foundation has no definition in the current criterion, causing diseconomy or safety loophole. The stress mechanism and demolition of the expanded-pier- foundation in rock foundation and foundation without rock are discussed. It is deemed that the bearing capacity of the expanded-pier-foundation should not be decided simply </span><a name=\"OLE_LINK36\"></a><a name=\"OLE_LINK35\"></a><span style=\"font-size:12px;line-height:1.5;text-align:justify;white-space:normal;\">on the ratio of length to diameter, and it should be confirmed rationally on the soil property. Furthermore, the structural design requirement of independent and pile foundation for the expanded-pier-founda- tion is proposed.</span>
