单桩承载力作为桩基设计与应用一项重要的参数依据.目前,静载试验是确定单桩承载力最直接、最可靠的方法,也是评价其他预估方法合理性的标准,但随着桩基施工技术的不断发展,桩径、桩长不断增大、增长,同时特殊场地(如狭小地段、边坡)的桩基施工也在不断增多,考虑到静载试验所需的试验条件,显然难以满足桩基发展的需要,如何合理的评价单桩承载力成为岩土工作者研究的主要方向之一.本文通过工程实例将静力触探与数值模拟预估单桩承载力成果对比分析,为今后的桩基设计工作提供参考.

The single pile bearing capacity is an important parameter to the pile foundation design and ap-plication.At present, the static cone penetration is the most direct and reliable method to confirm the single pile bearing capacity and the standard to appraise whether other methods are reasonable.However, with the develop-ment of pile foundation construction technology pile diameter and length are increasing while the pile foundation construction in special field such as narrow side and distract becoming more and more.It's difficult to meet the needs of the development of pile foundation in the view of test condition of static loading test.How to evaluate single pile bearing capacity becomes a main research direction.This article provided a reference for pile founda-tion design in future using engineering project cases to contrast and analyze the single pile bearing capacity result estimated by the static cone penetration test and numerical simulation.
