液压夯实技术在高速公路台背回填中的应用

摘要

为了解决桥头跳车问题，联合高等院校，在广西六钦高速桥涵台背回填完成后，对桥头及明涵台背进行了HHT-3液压夯实补强。本文在阐述HHT-3液压夯实机工作原理，介绍了液压夯实工艺以及在高速公路台背回填中的应用，希望对类似工程有一定借鉴作用。%In order to solve the problem of bridgehead bump, by jointing institutions, the paper conducted HHT-3 hydraulic tamping to the bridgehead and abutment backfill after Guangxi Liuqin expressway bridge abutment backfill. This paper expounds the working principle of hydraulic tamping process as well as its application in expressway abutment backfill, to provide experience for similar projects.
