摘要
通过室内试验研究了红黏土、纤维土、石灰土和纤维石灰土在浸水条件下的抗剪强度指标。基于试验结果,采用FLAC^(3D)软件对纤维石灰土路基边坡安全系数进行数值计算。计算结果表明,纤维石灰土路基边坡安全系数为红黏土路基边坡的2.1倍,红黏土填料中添加玻璃纤维和石灰对路基边坡稳定性有显著影响。研究结果可为类似工程提供借鉴。
The shear strength parameters of red clay,and red clay reinforced by fiber,lime,were studied by laboratory tests.Based on the experimental results,safety factor of red clay embankment reinforced by fiber and lime were calculated by using FLAC3D software.The safety factor of red clay embankment reinforced by fiber and lime is 1.12 times higher than the embankment filled with red clay.Glass fiber and lime reinforced red clay fillers have a significant influence on the slope stability of embankment.This study is of reference value to construction and design of other similar projects.
