浙江山地丘陵区公路工程弃渣处理探讨

Spoil disposal of road in the hilly area of Zhejiang Province

在山地丘陵区公路工程建设过程中,受地形等条件影响,往往开挖弃渣点多、量大,若弃渣防护不当,极易产生水土流失危害。根据工程区实际情况,提出浙江山地丘陵区公路工程项目弃渣处理的基本原则,并以浙江省龙庆公路庆元段(545、5省道)改善工程为例,论述山地丘陵区公路工程弃渣处理的具体方法及针对不同类型弃渣场的防护措施。

The harm of soil erosion could be easily brought by excavation and a large number of spoil without appropriate soil protection measures under the influence of topographical conditions during the period of highway construction in hilly lands. Based on the experiences of construction, the basic principles of road spoil disposal in hilly area of Zhejiang Province were put forward. Taking the restoration engineering works of Qingyuan line of Long Qing highway （54 and 55 provincial highway） in Zhejiang Province as an example, the approach to dispose the spoil of road in hilly area and the protection measures for different spoil areas were discussed.
