寒冷重冻地区路基边坡“浆砌片石满铺防护”的改进研究

针对黑龙江省常用的"平滑式"路基边坡浆砌片石满铺防护措施的应用情况,分析其所存在的缺点,通过研究相应的改善措施,提出了一种适合黑龙江省等寒冷重冻地区,且能改善路基边坡浆砌片石满铺防护使用功能、使用寿命的实用新型台阶式浆砌片石路基边坡满铺防护。该防护形式除增加10%左右建设期造价外,在结构耐久性、维修养护施工简便性、病害发展可控性和降低维修成本等方面,都具有明显的优势。

Study on Improvement of Spread Protection by Mortar Rubble for Subgrade Slope in Cold & Heavy Frozen Areas

In relation to the application of smoothing spread protection by mortar rubble for subgrade slope commonly used in Heilongjiang province, the disadvantages thereof were analyzed, furthermore, by studying the related measures for improvement, a new utility benched solution, which may improve the performance and service life of such protection measures and is applicable to the cold and heavy frozen areas in Heilongjiang province, was proposed. This new protection method except the increment about 10 % in the project cost in construction period did well in durability of structure, simplicity of maintenance, controllability of disease development and reduction of repair cost.
