摘要: 应用便携式落锤弯沉仪(PFWD)对导弹发射阵地强度进行评估,建立了发射阵地不同结构层模量和厚度条件下的PFWD冲击响应模型.根据数值计算结果,基于惰性点理论,对弹性半空间体系下的地基模量反演公式进行了修正,使反演公式更加符合工程实际.结果表明:利用PFWD可构建导弹发射阵地强度参数的无损检测系统,实现阵地强度参数的快速检测和评估.Abstract: Aiming at the intensity evaluation of missile launching site,the impulse response model in condition of different structure modulus and thicknesses is built by applying PFWD.According to numerical computation result,the inversion formula of subgrade resilience modulus in elastic semi-infinite body is reformed based on theory of inertial point,and the reformed inversion formula can meet the engineering reality better.The result shows it is feasible to construct nondestructive testing system of intensity parameter of missile launching site with PFWD and realize the fast detection and evaluation of intensity parameter.
