中文摘要：
复杂场地条件、高承载、异型结构、超长、复合材料等的桩基础发展趋势,使得桩基础极限荷载准确确定愈发重要,实现传统手段的桩基础极限荷载确定方法也面临较大困难.文中分析了原位试验方法、经验公式方法和数值仿真试验方法的三类共9种确定方法的优缺点和适用条件,表明依据桩基础特性选用适当的极限荷载确定方法的重要性,且加强使用数值仿真计算方法辅助试验手段,降低试验检测成本,将对工程建设经济性、安全性意义重大.
英文摘要：
There are the developing trend of pile foundation in the complex field, high bearing capacity, abnormity pile body, super-length and composite. These will be important to estimate the ultimate load of pile foundation, and the traditional methods are difficult to estimate ultimate load of pile foundation. The 9 estimation of 3 class methods of in-situ testing, experimental formula and numerical simulation is analyzed in the field of merits and drawbacks and the application condition. It is important to choose the suit method for estimating the ultimate load on the base of the characteristic of pile foundation. And the numerical simulation is also intensively studied for the subsidiary of testing methods. It will decrease the testing cost, and is important for the economy and safety of engineering construction.
