西部山区公路泥石流的选线与整治实践

Route Selection and Treatment of Highway Hebris Flow in Western Mountainous Area

西部山区地质灾害频发,公路选线必须考虑泥石流等地质灾害影响,217公路通过天山北坡中高山区,泥石流等地质灾害频发,严重危害线路的运行安全,因此,基于泥石流形成区的活动特征,进行公路的选线和工程整治措施,为线路的安全运行打下可靠基础。

Geological disasters occur frequently in the western mountainous area,so the influence of debris flow and other geological disasters must be considered in highway route selection.As the 217 highway passes through the middle and high mountain area on the north slope of Tianshan Mountain,the geological disasters such as debris flow occur frequently,which seriously endanger the operation safety of the line.Therefore,based on the activity characteristics of debris flow,the route selection and engineering treatment measures of highway are carried out to lay a reliable foundation for the safe operation of the line.
