| 摘 要： | 为更加充分的了解龄期及桩身位置对桩身强度的影响,通过工程实例研究了桩底、桩身及桩底不同部位不同龄期的桩体无侧限抗压强度值,提出水泥搅拌桩设计过程中尽可能提出对于不同部位水泥搅拌桩桩身强度值,避免以单一桩身强度值来明确整条桩体的情况;必要时可通过28 d或60 d龄期强度作为评定标准。

| Abstract: | In order to understand the influence of the effect of ages and the sampling positions on the strength of the pile, unconfined compressive strength of different ages and positions have been studied through an engineering example. Different unconfined compressive strengths should be used in different positions to determine the whole pile''s compressive resistance. And 28d or 60d age strength can be used as evaluation standard when it is necessary in test. |

| Keywords: | cement mixing pile ages detection unconfined compressive strength |
