红层软岩环境下某站场高填方工程设计

Design of High-fill Slope for a Natural Gas Station in Red Bed Area

红层软岩是一种特殊岩土,具有抗压强度低、易风化、遇水易软化、崩解、膨胀、填筑密实度对含水量很敏感等特点,大量的红层地区填料工程实践表明,红层地区软岩填料在填方工程中引发的边坡病害问题非常严重。论文结合工程实例,对这类填方工程的填筑工艺和边坡防护设计进行分析探讨,总结相应工程经验,以供类似工程参考。

Red bed soft rock is a kind of special soft rock, with low compressive strength, easily weathered, easy to water softening, collapse, expanding and the dense degree is very sensitive to moisture. A large number of filling practice in red bed area prove that there exists serious disease problem when making filling slopes with this kind of paddings. In this paper, combining a project case, the filling process and slope protection design for this kind of high-fill slope are analysed and discussed, the corresponding experience available for reference is summarized finally.
