岩土应力应变匹配传感器的研制及应用

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。

Development and Application of Rock Soil Stress Strain Mate Sensor

A new type of undirectional rock soil mate sensor is developed to be used in soft rock and similar material model to survey pressures and deformations. The elastic modulus of the elastic element is equal to that of the measured rock soil. The stress and strain of the rock soil can be quantitatively surveyed. It can survey both of the pressure and deformation at the given point in the rock soil or similar material. The measurement ranges are suitable for soft rocks and similar materials or soils with satisfactory repeatability and stability.
