摘要
通过对湖南地区已建成的公路水泥混凝土路面使用状况调查 ,发现本地区混凝土路面断板病害的主要原因之一是水冲刷引起的板下掏空。分析了发生水冲刷破坏的结构、材料、设计和施工等方面原因 ,提出防止混凝土路面水冲刷破坏的对策及措施 。
Investigations indicated that broken slabs of PCCP is mainly due to water erosion of the base layer in Hunan Province. In this paper, causes in structure, materials, design and construction, which may result in the water erosion damage, are analyzed, and measures to deal with the damage are suggested.
