调研了我国公路路面中出现的局部快速水损坏现象。分析了其主要原因是局部路基沉降,明流排水不通畅,路面局部低洼积水;渗透排水管沟堵塞,路基土体泥化,丧失承载能力。得出了路基隔振的新要求及路床水分冷凝迁移富集的新机理,提出了新编公路交通行业《公路防排水工程施工与质量检验规范》的建议,以完善我国公路防排水技术,保证公路路基工程的水稳定性与长期运营承载能力。
The phenomenon of local rapid water damage appearing in the road surface of our country was investigated. The main reason for the analysis is the settlement of partial roadbed, unobstructed drainage in the Ming River, partial low-lying water accumulation in the pavement, blockage of seepage drainage ditches, muddy soil in the subgrade, loss of carrying capacity. The new requirements of roadbed vibration isolation and the new mechanism of roadbed moisture condensation and migration and enrichment are obtained, and a new road traffic industry “highway drainage and drainage engineering construction and quality inspection specifications” recommendations to improve China’s road drainage technology, Guarantee water stability and long-term carrying capacity of highway subgrade engineering.
