陶鄂铁路路基坡面防冲刷设计原则研究

Study on Anti-erosion Design Principles of Subgrade Slope for Taolimiao-Etuokeqianqi Railway

陶鄂铁路路基填料主要采用风积沙,风积沙路基边坡在雨后极易遭到冲刷破坏。在分析边坡冲刷影响因素和冲刷破坏形成过程的基础上,本文重点对陶鄂铁路路基坡面防冲刷防护原则进行研究,针对不同的路基填筑高度,分别采用混凝土预制板、树枝沙障、混凝土六棱空心砖、骨架护坡等防护形式,可有效减少路基冲刷破坏,满足疏排水要求。

The subgrade filler of Taolimiao-Etuokeqianqi railway is mainly used by aeolian sand, which is vulnerable to erode after the rain. Based on the analysis of slope erosion factors and formation process, this paper focuses on the anti-erosion design principles of subgrade slope. According to different height of subgrade, respectively, the subgrade slope utilizes precast concrete panels, branches sand barrier, six edges of concrete cinder block, skeleton slope, etc. These forms of protection can effectively reduce the erosion damage and meet the drainage requirement.
