摘要
利用特征线方法数值模拟计算了应力波在截面或弹性模量连续变化的弹性杆中的反射,同时也讨论了应力波脉冲宽度对反射波波形特征的影响,其结果对桩基测量有一定的参考价值。
In this paper, reflection of stress-wave in an elastic bar with continuously varying cross-section area or modulus of elasticity is calculated by numerical simulation based on charcteristic-line method, effect of stress wave pulse width on character of reflecting wave form is discussed also. The results are helpful for pile foundation measurement.
