针对实际工程中岩体边坡加固技术的不足,从边坡稳定内因出发,基于提高边坡岩体自身抗剪强度的思想,提出了压力注浆加固的方法.从力学机理出发,研究了注浆胶结体对加锚弱面力学性能的影响,在力学基础上为注浆工艺提供了论证.通过ANSYS建立数值模型,利用本文自编ANSYS-FLAC3D转换程序导入FLAC3D进行数值分析,在分别改变弱面抗剪强度参数c、φ值的条件下,得到c、φ与安全系数K之间的关系.分析结果表明,通过注浆提高弱面的c、φ值,能够从本质上提高边坡的稳定性.研究结果为岩体边坡压力注浆加固方法提供了可靠依据.

英文摘要：

Aiming to the shortage of the reinforcement method in rock slope, from internal cause of slope stability and based on the thought of increasing the self-shear-strength of rock mass, the method of compressive grouting is put forward. Based on the mechanics characteristic, the influence of grouting to the weakness plane with bolt is studied, and a demonstration for the grouting technics is provided, A numerical model is founded by ANSYS, according to ANSYS-FLAC3D self-write conversion program, the model is conducted into and calculated by FLAC3D. By changing shear strength parameters c, Ф, the relations between c, Ф and safety factor g are obtained. The analysis result shows that by grouting the value of c,Ф are highly increased, and the stability of slope is increased essentially. Finally, the conclusions provide reliable references for the method of compressive grouting in reek slope.
