摘　　要：根据已投入运营的和正在建设的高速公路不难看出,当前,我国高速公路仍普遍存在垂直开裂、沉陷、滑坡、坡脚拱起等病害。造成这一现象的原因有很多方面,其中一个主要原因就是当前我国还没有设置专门的路基基底承载力指标。因此,不同的建设单位往往使用不同的检测手段,造成检测的承载力数据通常大相径庭。论文简要阐述了高速公路承载力检测方法,结合工程实例对使用荷兰轻型动力触探仪进行高速公路承载力检测予以介绍,旨在为类似项目提供参考。According to the expressway that has been put into operation and the expressway that is under construction,it is not difficult to see that the current expressway in our country still generally exists such faults as vertical cracking,subsidence,landslide and arch of slope foot.There are many reasons for this phenomenon,and one of the main reasons is that there is no special index of subgrade basement bearing capacity in China.Therefore,different construction units often use different means of monitoring,which results in the measurement of carrying capacity data are usually very different.This paper briefly describes the highway bearing capacity detection method,introduces the expressway bearing capacity testing with Dutch light dynamic contact instrument?combined with engineering examples,so as?to provide reference for similar projects.
