一、概述水电部南京水电仪表厂原生产的应变式直剪仪系五十年代初期产品,普遍反映该仪器陈旧笨重。目前不少使用单位己对该仪器进行了改进,大多侧重于室内电动,自动记录和野外轻便化几个方面。这些改革对于改变土工仪器落后面貌与提高试验效率都起了一定作用。 75年底我们对原直剪仪进行改革,改革中考虑到既要在技术上革新,又要保持原直剪 First, an overview of the Ministry of MEP Nanjing Hydropower Factory original strain gauge strain gauge early 1950s products, generally reflect the heavy equipment obsolete. At present, many users have made improvements to the instrument, most of which focus on indoor electric, automatic recording and field lightness. These reforms have played a certain role in changing the backwardness of geotechnical instruments and improving the test efficiency. At the end of the year 75, we carried out the reform of the original straight shear device. In the reform, we must take into consideration that both technological innovation and original straight shear
