黄土地区公路排水工程通病及防治措施

Common Diseases and Prevention Measures of Highway Drainage Engineering in Loess Area

引起我国黄土地区公路各种常见病害的原因中,水的原因是主要之一,但是黄土地区公路的排水工程在设计和施工中均未得到足够的重视。由于黄土地区地质、地形以及土壤特征的特殊情况,特别是黄土的湿陷性,更易导致黄土地区公路出现病害。因此必须对于黄土地区公路排水设施从设计到施工、养护都要引起足够的重要,并做好相应的防治工作。

Water is one of the main causes of various common diseases of highway in Loess area, but the drainage engineering of highway in loess area has not been paid enough attention in design and construction. Because of the special geological, topographic and soil characteristics in the Loess area, especially the collapsibility of loess, it is easier to cause highway diseases in the Loess area. Therefore, it must be important enough for the design, construction and maintenance of highway drainage facilities in Loess areas, and do a good job of prevention and control.
