宁夏地区公路病害特征及其成因分析
|
Abstract:
宁夏属于典型的季节冻土区，季节冻土区的公路因受气候、环境及周期性冻融循环作用的影响，极易产生路基路面病害，给公路运营带来严重影响。因季节冻土表现出很强的地域性，宁夏地区独特的自然与地理条件使该地区的公路病害也具有地域性特征。专门针对宁夏地区公路病害特征的研究既紧迫又势在必行，通过对宁夏地区北部、中部及南部部分市区内道路、部分国道及省道典型路段的路面病害特征进行调查研究，并对病害的成因进行分析，以期为宁夏地区的公路建设以及病害防治提供借鉴和参考。
Ningxia is a typical seasonal permafrost area, and the roads in the seasonal permafrost area are susceptible to roadbed and pavement diseases due to the influence of climate, environmental and periodic freeze-thaw cycles, which bring a serious impact to the road operation. As seasonal permafrost shows strong regional characteristics, the unique natural and geographical conditions of Ningxia region make the road diseases in this region also have regional characteristics. It is urgent and imperative to study the characteristics of highway diseases in Ningxia region. By investigating the characteristics of pavement diseases in some urban roads, some national highways and provincial roads in the north, central and south Ningxia region, and analyzing the causes of the diseases, we aim to provide a reference for the construction of highways and disease prevention and control in Ningxia region.
