【摘要】 针对当前岩土工程试验中采用人工读数测试存在的慢速度,低效率问题,设计开发了一种计算机在线动态测试系统。该文从在线动态测试系统原理及硬件构成、软件组成及功能方面详细介绍了计算机动态测试系统研发思路。并采用开发的岩土工程测试系统,对云锡松树脚锡矿矿岩试件进行了不同荷载条件下的强度-变形试验。试验表明,采用该系统,测试频率达到每秒30条数据记录,测试数据完整反映了岩石破坏过程中的应力变化。计算机在线测试系统方便、快捷、准确、反映了被测对象的特性,实现了多点在线实时追踪数据变化的动态不间断测试。更多还原

【Abstract】 According to the problems of slow speed and low efficiency in artificial test for the current geotechnical engineering experiment, a kind of computer online dynamic test system is designed and developed.Here,the developing ideas of this system are introduced from its principles,hardwares,softwares and functions,at the same time,the intensity-deformation tests are made for the rock samples under different load conditions by uning this test system.The test results show that the system is convenient,accurate and practical to reflect the characteristics of the object,and could achieve the multi-point online and real-time tracking test in dynamic and uninterrupted conditions.更多还原
