以大阳山隧道工程为例，拟建苏州大阳山隧道穿越地段岩性多样复杂，为了研究该地段岩石的强度指标及其相互关系，测试了代表性岩石的点荷载强度、单轴抗压强度、回弹强度，并用幂函数、指数函数、线性函数拟合3种强度的相关关系。结果显示：用幂函数来拟合点荷载强度与单轴抗压强度更佳；用指数函数来拟合回弹强度与单轴抗压强度、回弹强度与点荷载强度更佳；其相关公式可以用来预测岩石的单轴抗压强度以减少室内试验的数量；另外发现岩石的单轴抗压强度对拟合的精度有一定的影响，在运用公式预测时应注意精度的要求。

The point load strength,uniaxial compressive strength and rebound strength of representative rocks in Dayangshan tunnel project were tested,and the correlation among them was fitted by power function,exponential function and linear function.The results show that it’s better to use power function to fit the relationship between point load strength and uniaxial compressive strength,and exponential function to fit the relationship between re-bound strength and uniaxial compressive strength,point load strength and rebound strength.In order to reduce the number of laboratory tests,we use these related formulas to predict the uniaxial compressive strength of rock.More-over,uniaxial compressive strength has influence on the fitting accuracy,which should be considered in the predic-tion.
