摘要: 通过预应力锚杆加固后边坡安全系数和锚固力的计算,得出预应力锚杆布置参数对于计算边坡安全系数的作用至关重要。在边坡例证搜集数据的基础上,运用FLAC3D软件对锚杆支护效果进行数值模拟,运用Matlab软件对模拟数据进行拟合,得出相应的曲线图。利用回归分析中的多元线性回归进行计算,从而确定了锚杆布置参数与边坡安全系数的相关性。Abstract: The calculation of slope safety and the anchoring force of the prestressed bolt show that bolt installation parameters are crucial for calculating slope safety coefficient. Based on the collec-tion of a set of data, using FLAC3D software for numerical simulation of the bolt support and Matlab software to fit the data, the corresponding curve was gotten. By using multivariable liner regression to calculate the fitting curve, the correlation between bolt installation parameters and slope safety coefficient was determined.
