中文摘要：

锚杆框架梁是加固膨胀土路堑边坡的一种方式，能够有效地抑止膨胀土边坡裂隙的扩展和发展，阻止边坡体的变形。为了研究锚杆框架梁的加固效果及其坡率对膨胀土路堑边坡的影响，采用了快速拉格朗日差分分析三维软件FLAC^3D模拟锚杆框架梁加固膨胀土路堑边坡。数值分析及结果表明，坡率与膨胀土路堑边坡变形密切，锚杆框架梁参数中锚杆布设角度和间距对膨胀土边坡变形影响较大，同时对锚杆框架梁的主要参数提出相关的建议，为工程和设计优化提供了参考。

英文摘要：

Anchor frame beam is a method for strengthening the expansive soil roadcut slope. It can effectively prevent cracks and fissures of expansive soil slope from expanding. Thus it can preclude the slope from being destroyed. FLAC^3D software is used for simulating anchor frame beam strengthening expansive soil roadcut slope. Main parameters such as length, range interval and angle of anchor frame beam, are investigated so as to acquire how to influence slope deformation. The results show that the ratio of slope has an impact on slope deformation; and that the angle and the range interval of anchors influence slope deformation. The pertinent proposal for design of main parameters of anchor frame beam is put forward so as to offer reference for engineering optimum design.
