摘　　要：文中采用塑料锤敲击建筑构件,激发固体声波,进行纵向声波波速的现场测量,由此确定已完工的建筑构件的杨氏模量。该实验方法可以在不损建筑结构和表面装饰的情况下,进行现场实测,而且具有精度高、简便的特点。The structure-borne sound which excited by plastic hammer hitting structure surface is used to measure the longitudinal wave speed of in-situ buildings,hence the determination of the Young's modulus.The measurement can be simply and accurately employed to obtain the Young's modulus without damaging the structure and marking decorating finishes.[
