通过对淮南矿区岩石取样进行点荷载与岩石强度试验及结果分析,用最小二乘法对试验数据进行线性拟合,得出了点荷载与岩石抗压、抗拉强度之间的曲线拟合方程。将实验数据代入线性方程进行了验证和对比,拟合曲线基本符合试验数据的分布规律,分段拟合对减小误差具有更好的效果。 Through the point load and rock strength test and the result analysis of the rock samples in Huainan mining area, the curve fitting equation between the point load and rock compressive strength and tensile strength was obtained by using the least square method to fit the test data. The experimental data are substituted into the linear equation for verification and comparison. The fitted curve basically accords with the distribution of experimental data, and the piecewise fitting has a better effect on reducing the error.
