我国经济发展水平不断提高,对于公路交通的要求也就越来越高。车辆通行数量和频率的快速增长,使得公路路基承受的交通荷载量越来越大,极容易出现路基沉陷问题。同时,公路工程设计和施工上的不合理也是造成公路路基沉陷的重要原因。本文首先对公路路基沉陷进行简要阐述,进而对沉陷的主要原因进行探究分析,并提出有效的处理措施,以期为我国公路路基维护和公路交通事业发展提供有效借鉴。
The continuous improvement of China’s economic development has also raised the demand for road traffic. The rapid growth of the number and frequency of vehicles makes the traffic load on highway subgrade more and more prone to roadbed subsidence. At the same time, unreasonable highway engineering design and construction is also an important reason for subsidence of highway subgrade. In this paper, firstly, the subgrade settlement of highway is briefly described, then the main reason of subsidence is analyzed and analyzed, and the effective treatment measures are put forward to provide an effective reference for the maintenance of highway subgrade and the development of highway transportation in our country.
