为了确定混凝土的状态方程(Eos，Hugoniot)性质，进行了两个不同且独立的冲击压缩试验。本研究中使用的技术是全尺寸爆轰实验，其中使用碳电阻计获得受影响混凝土体内的压力，以及飞板撞击实验，其中随后的速度历史由VISAR(任何反射面的速度干涉仪系统)监测，并通过守恒方程估计相关的压力和密度。不同的试件是用混凝土制成的，装料相同。这些实验是在不同的实验室地点进行的，但同时进行。这两种方法的压力密度数据最高可达16 Gpa。开展这项调查是为了评估两种不同方法对Eos数据的有效性。据作者所知，这是以前从未做过的。(C)2005爱思唯尔有限公司。保留所有权利。
Two different and independent shock compression experiments have been performed in order to determine equation of state (EoS, Hugoniot) properties of concrete. The techniques used in the present study are full-scale detonation experiments where pressures were obtained in the affected concrete body with carbon resistor gauges, and, flyer-plate-impact tests where subsequent velocity histories were monitored by a VISAR (velocity interferometer system for any reflector) and the related pressures and densities evaluated by means of the conservation equations. The different specimens have been produced with concrete out of the same charge. The experiments were performed in different laboratory locations but at the same time. Pressure-density data are reported from both methods up to 16 GPa. The investigation has been carried out in order to assess the validity of two different methods with respect to EoS-data. To the knowledge of the authors, this has not been done before. (C) 2005 Elsevier Ltd. All rights reserved.
