边坡工程中锚杆加固边坡的机理是岩土工程领域中的重点研究课题。结合幕府山边坡治理工程的实例,采用FLAC3D数值方法对边坡进行稳定性计算,分析了治理后的边坡在锚杆支护前、支护后的稳定性,研究了在未支护情况下边坡的最危险滑动面的确定以及支护后不同位置处锚杆的轴力和水泥浆粘结强度分布规律和加固机理。
The mechanism of bolt reinforcement slope in slope engineering is a key research topic in the field of geotechnical engineering. Combined with the example of the Mufu Mountain slope control project, the stability of the slope was calculated by FLAC3D numerical method. The stability of the treated slope before and after bolting was analyzed. In the case of unsupported condition The determination of the most dangerous sliding surface of the lower slope and the distribution of the axial force and the bond strength of the cement slurry and the reinforcement mechanism at different positions after the support.
