公路路基常见病害及路基加固技术研究

Research on Common Subgrade Diseases and Subgrade Reinforcement Technology

公路路基的好坏对公路运行状况和使用寿命有重要影响,对路基进行加固也是保证路基工程质量的重要措施。本文针对公路路基病害产生原因进行了分析,然后提出了换填路基土法、注浆加固法、加筋法和桩基加固法四种路基加固技术,为有效解决公路路基病害提供了技术支持。

The quality of the highway subgrade has a significant impact on the operating condition and service life of the highway.Reinforcement of the subgrade is also an important measure to ensure the quality of the subgrade engineering.This paper analyzes the causes of highway subgrade diseases,and then proposes four subgrade reinforcement technologies,such as soil replacement method,grouting reinforcement method,reinforcement method,and pile foundation reinforcement method,which provide technical support for effectively solving highway subgrade diseases.
