针对柔性支护系统在边坡防护应用中按工程经验进行设计的现状,利用FLAC3D对实体工程中典型风化岩质路堑边坡在采用3种柔性支护系统后的稳定性能指标进行了定量分析。结果表明:简单维护和加筋维护系统的加固性能相近且加固效果较弱;主动加固柔性支护系统加固效能优异,其边坡安全系数增幅、最大位移减小量分别为前两种系统的4倍和1.5倍,并能有效地减小边坡的受力;各柔性支护系统对边坡局部失稳的防护效果明显优于对整体失稳的防护效果。 Aiming at the current situation of flexible support system designed according to engineering experience in slope protection application, the stability indexes of typical weathered rock slope in solid engineering using three kinds of flexible support system are quantitatively analyzed by FLAC3D. The results show that the reinforcement performance of the simple maintenance and reinforcement system is similar and the reinforcement effect is weak. The reinforcement effectiveness of the active reinforcement and flexible support system is excellent. The slope safety factor increase and the maximum displacement reduction are respectively 4 Times and 1.5 times, and can effectively reduce the stress of the slope; the protective effect of each flexible support system on the local instability of the slope is obviously better than the protective effect on the overall instability.
