| 岩石单轴抗压强度是嵌岩桩嵌岩段极限侧阻力计算的关键参数.本文介绍了基于点荷载试验计算岩石单轴抗压强度的方法，给出了岩石极限侧阻力系数与岩石单轴抗压强度之间的拟合关系式，由此可计算确定岩石极限侧阻力系数，从而提出了一种利用岩石点荷载试验计算嵌岩桩嵌岩段极限侧阻力的方法，可作为嵌岩桩工程设计的参考. |

| The uniaxial compressive strength of rock is the key parameter for calculating the ultimate side shear resistance of rock-socketed piles.In this study，the method of calculating rock uniaxial compressive strength based on rock point load test was firstly introduced.Then，according to the fitting formula between ultimate side shear resistance factor and uniaxial compressive strength of rock，the ultimate side shear resistance factor can be calculated.As a result，the ultimate side shear resistance of piles socketed into rocks can determined by utilizing point load strength test results，which can be used in engineering practice of rock-socketed piles. |
