摘要
水毁严重影响新疆315国道正常运营和安全。凹岸冲刷,压缩冲刷,路面淹没后急速退水对路面和路肩的冲刷,泥石流冲刷、淤埋和堵塞是水毁破坏公路的常见形态;从气候及地质构造和公路自身建设缺陷系统分析了新疆315国道茫崖-且末段公路水毁的原因;通过模型试验分析得出格宾箱体结构和格栅笼具有较强的抗冲刷能力,并将两种防护型式与传统浆砌挡墙等结合应用于现场试验路段,试验结果表明,所提出的治理技术具有较强实用性及经济优势。
The flood damage seriously affects the safety and normal running in 315 national highway.there are some major damage patterns of flood damage,that is ＂curve road concave bank＂,＂ Compression erosion＂,＂erode after recession flow on pavement＂ and ＂erosion,deposition and blockage of debris flow＂.This paper systematically analyzes the forming environment of the flood damage at section from Mangya to Qiemo in Xinjiang 315 national road based on study of environment and climate conditions,the geological condition of riverbed,the deficiency on road construction.Box cabinet structure and grating cabinet structure have the stronger erosion resistibility;the protection effect is tested through the physical model examination in laboratory.Two types of defending are used in combination with the traditional mortar retaining wall in field test.The result indicates that these two technology have a better practicability and economic advantages.
