水是高速公路在使用过程中出现病害的重要原因,高速公路在施工或营运过程中路基土中含水量过大导致路基强度降低或失稳,进而产生路面破坏。文章在对实体工程路基土含水量和压实度变化规律试验的基础上,分析了含水量过大和压实度降低的成因;提出有效的降低路基土含水量防治技术。工程实际表明,处治效果良好,相关技术措施可为相同地区高速公路建设提供借鉴和参考。
Water is an important cause of the disease in the process of using the expressway. When the water content of the subgrade soil during the construction or operation of the expressway is too large, the strength of the subgrade declines or becomes unstable, which in turn causes road damage. Based on the test of the variation law of water content and compaction degree of subgrade soil in solid engineering project, the paper analyzes the causes of the excessive water content and the decrease of compaction degree, and puts forward the effective prevention and control technology of subgrade soil water content. Engineering practice shows that the treatment effect is good, the relevant technical measures for the same area of highway construction to provide reference and reference.
