摘　　要：圆锥动力触探作为原位测试技术之一,具有设备简单、方便快捷、成本低等优点,成为检测地基承载力的首选方法。由于一些天然地基的特殊性不适用于静载试验,业主单位选择动力触探进行地基承载力的检测,针对实际工作中遇到的如何确保数据的准确性、检测深度和碎石土承载力判定问题进行探讨,并提出建议。Because of its simplicity,high speed and low cost,dynamic penetration test is one of the in-situ test techniques and it has become one of the preferred methods to test the bearing capacity of foundation.Due to the particularity of some natural foundations,which are not suitable for static loading tests,the owner chooses dynamic penetration test to test the bearing capacity of the foundation.This paper discusses how to ensure the accuracy of data,detection depth and judgment of bearing capacity of crushed stone soil,and puts forward some suggestions.
