岩土单向应力应变匹配传感器，是最新研制的应用于岩土及相似材料模型等效压力，变形量测的匹配型传感器，其弹性元件的弹性模量与被测岩土的弹性模量相等，属于岩土应力应变定量测量型传感器。它可以同时测得岩土被测点的压力和变形量。经过在相似材料模型上的应用，其重复性、稳定性等技术指标满足了岩土和相似材料模型的测试。可测量岩性为软岩和具有一定弹性模量的相似材料及土壤等的应力应变。
Rock and soil unidirectional stress and strain matching sensor is a newly developed matching sensor applied to equivalent pressure and deformation measurement of geotechnical and similar material models. The elastic modulus of the elastic element is equal to the elastic modulus of the rock under test , Belonging to geotechnical stress and strain quantitative measurement type sensor. It can measure the pressure and deformation of the measured point of rock and soil at the same time. After the application on the similar material model, the technical indicators such as repeatability and stability meet the test of geotechnical and similar material models. Can measure lithology as soft rock and a certain elastic modulus of similar materials and soil stress and strain.
