摘　　要：设计的新型预应力实验综合测试系统,采用了液压加载装置实现连续动态加载,测量试件所承受的压力和预应力筋的变形,通过预应力综合数据管理系统,将检测到的应力、应变数据在计算机上进行分析,并生成符合国家标准的检验报告,实现了试验数据不能人为更改和直接查询打印的功能,从而确保了试验的准确性、公正性和规范性。A new-type prestressed comprehensive test system is designed, and the hydraulic loading device is applied to realize continuous and dynamic loading, so as to measure the pressure of the test piece and the deformation of prestressed rib. The prestressed comprehensive data management system is used to analyze the measured data of stress and strain and then output inspection reports conforming the national standard. The report can not be altered arbitrarily by anyone and can be directly checked and printed, which guarantee the accuracy, equity and normalization of the test.
