原文研究了波动在传递过程中能量的衰减规律问题,从理论上评价了人工边界的波动反射效应,笔者曾在两座混凝土重力坝的原型振动试验中从坝体与基岩相互作用问题入手,探讨了这一问题,现简述如下。 The paper studied the law of energy attenuation in the transmission process of fluctuation, and theoretically evaluated the wave reflection effect of the artificial boundary. The author started with the prototype vibration test of two concrete gravity dams and started from the interaction between dam body and bedrock. This issue has been explored and is briefly described below.
