基于自平衡测试技术，根据衡桂高速两根桩基的静载荷测试报告，对嵌岩桩的承载特性进行了研究分析，主要内容包括桩顶等效荷载位移曲线分析，桩周岩层侧阻力大小、桩周岩层侧阻力与位移关系、桩侧与桩端阻力分担比等。研究结果表明，该地区嵌岩桩桩顶的Q—s曲线主要是缓变型为主，属摩擦型桩。
基于自平衡測試技術，根據衡桂高速兩根樁基的靜載荷測試報告，對嵌巖樁的承載特性進行瞭研究分析，主要內容包括樁頂等效荷載位移麯線分析，樁週巖層側阻力大小、樁週巖層側阻力與位移關繫、樁側與樁耑阻力分擔比等。研究結果錶明，該地區嵌巖樁樁頂的Q—s麯線主要是緩變型為主，屬摩抆型樁。

Based on self-balanced testing technique, according to static load testing reports of two pile foundations on Heng-Gui highway, the paper analyzes and studies the bearing performance of rock-socketed pile including top pile equivalent load displacement curve analysis, lateral friction force of rock layer surrounding the pile, relationship between pile surrounding rock lateral friction force and displacement, and sharing ratio of lateral pile and pile end and so on. Research results show that top pile Q-s curve of the rock-socketed pile is slowly changed, which belongs to friction-style pile.
