利用岩石地基载荷试验推定单桩承载力

摘要

The vertical bearing capacity of artificial excavated rock-socketed single pile was usually higher. Because of the equipment,field conditions and many other restrictions,using single pile vertical compressive static load test to detect its bearing capacity was very difficult. Based on engineering examples,this paper introduced how to use rock foundation loading test to determine and calculate the bearing capacity of the foundation thus to determine the vertical compressive bearing capacity of a single pile.%人工挖孔嵌岩灌注桩单桩竖向承载力值通常较高，采用单桩竖向抗压静载荷试验检测其承载力，会受到设备、现场条件等诸多方面限制，试验作业难度很大。以工程实例为基础，介绍如何在人工挖孔嵌岩灌注桩基桩检测中，利用岩石地基载荷试验确定、核算岩石地基承载力，从而推定单桩竖向抗压承载力。
