摘　　要：对真空预压中真空荷载的几种主要表述方式进行了辨析,明确了真空度和真空压力的含义与区别,并对其应用范围提出了建议。对真空荷载的测量方式进行了研究,建议真空度的测量可采用真空表法或孔压计法,而真空压力的测量仅适合用孔压计法。The analysis is done for some main expressions of vacuum load in vacuum preloading project. The meanings of vacuum degree and vacuum pressure are interpreted, the difference between them is presented, and the application scope of these two expressions is suggested. This paper studies the measurement methods of vacuum load, the results suggest that the vacuum gauge method or pore pressure gauge method can measure the vacuum degree, but the pore pressure gauge method can measure the vacuum pressure only.

关 键 词：真空预压 真空度 真空压力 测量
