摘　　要：不确定度在质量管理和质量保证体系中极为重要。首次尝试将测量不确定度理论应用于桩基高应变检测的凯司法中,推导出了凯司法的测量扩展不确定度表达式,并将其应用于工程中。实践表明,在有效动静对比验证资料的基础上,该表达式完全能够满足工程的需要。Uncertainty takes an important role in quality administration and quality assurance system. The uncertainty theory was firstly applied in CASE method of high-strain dynamic pile testing. The expanded uncertainty expression formula of CASE method is deduced and being analyzed by engineering examples. The practice indicated that the expression formula can completely satisfy the engineering requirement.
