摘要
本文以湖田铝土矿不规则岩样点载荷试验为例，论述了用非线性回归分析方法确定标准点载荷指数Ｉ_（Ｓ（５０））、及岩石的抗压和抗拉强度。试验与计算表明，这一方法是准确可靠的。
Taking the point-load test for irregular rock samples from Hutian bauxite mine as an example,This paper describe that the nonlinear regression analysis method was used to determine the standard point-load index Is(50) and the compressive and tensile strength of rock.The test and calculation results have showed that this method is accurate and reliable.
