摘要
滑动测微计是了解桩周土层侧阻力和桩端阻力的主要方法,结合广东科学中心桩基试验的工程实例,介绍滑动测微计在桩身内力测试中的应用原理和方法,计算该工程试桩的极限侧摩阻力和端阻力以及弹性模量与应变的关系。
Sliding micrometer is a main method to measure side resistance of stratum around piles and resistance at pile tip. This paper introduces in details the application theory and method of sliding micrometer in the measurement of pile internal force according to practical pile foundation test in Guangdong Science Center project. Limit side friction and tip resistance as well as relation between elastic modulus and strain are calculated. These contents provide important references for optimistic design of pile foundation and pile test in similar projects.
