运用两点应变测量法的基本原理进行了圆柱形杆末端冲击力测试实验 ,理论值和实测结果取得了一致 ,验证了其可行性 ,并利用两点应变测量法对岩石的动态凿入特性进行实验研究 ,根据最小二乘法曲面拟合 ,得出了更为精确的凿入系数和粘度系数值 ,并在实验的基础上综合得到粘弹性类型岩石——泰山花岗岩力——凿深特性的一般模式 The basic principle of two-point strain measurement method was used to test the impact force of the end of the cylindrical rod. The theoretical and experimental results were consistent and the feasibility was verified. The two-point strain measurement Based on the experimental data and the least-square fitting method, the more accurate values ​​of the chisel penetration coefficient and the viscosity coefficient are obtained. Based on the experiments, the general characteristics of the viscoelastic type rock-Taishan granite are obtained mode
