鉴于海洋地质、内河勘察、地下工程、石油钻探以及土壤研究的需要,我们借鉴国外仪器的特点设计了袖珍十字板剪力仪。该仪器测量速度快,在5～10秒钟内即可测出土质的抗剪强度值。它体积小,重量仅有0.4公斤。本文从国内剪力仪概况和袖珍十字板剪力仪的工作原理、使用方法、应用范围及设计等方面做一简略介绍。 In view of the needs of marine geology, river exploration, underground engineering, oil drilling and soil research, we have designed pocket cross shear shears based on the characteristics of foreign instruments. The instrument measuring speed, in 5 to 10 seconds to measure soil shear strength value. It is small, weighs only 0.4 kg. This article makes a brief introduction from the general situation of domestic shears and the working principle, usage method, application range and design of the pocket wedge shears.
