摘要 1962 年，Kondner 撰写了几篇关于粘性土的双曲应力-应变响应的论文。次年，Brinch Hansen 提出了粘性土应力应变行为的 80% 和 90% 失效准则。 Fellenius 在推广这些桩荷载试验失效准则方面发挥了重要作用，并根据 80% 失效准则提供了失效荷载的直接求解方程。由于 90% 标准已纳入国际建筑规范，因此直接求解 90% 标准下失效荷载的方程对于实践工程师来说将非常有用。本技术说明提供了 80% 标准的推导方法，并提供了确定 90% 标准失效时的载荷和挠度的表达式。
Abstract In 1962, Kondner prepared several papers dealing with hyperbolic stress-strain response of cohesive soils. The following year, Brinch Hansen proposed 80% and 90% failure criteria for stress-strain behavior of cohesive soils. Fellenius was instrumental in popularizing these failure criteria for pile load tests and offered a direct solution equation for the failure load according to the 80% failure criterion. Since the 90% Criterion has been incorporated into the International Building Code, equations for the direct solution of the failure load at the 90% Criterion would be useful to practicing engineers. This Technical Note supplies the derivation methodology for the 80% Criterion and provides expressions to determine the load and deflection at failure for the 90% Criterion.
