| description | The utility model discloses a soil-rock mass in-situ direct shear test device with an automatic data acquisition system, and relates to a soil-rock mechanics test technology. The soil-rock mass in-situ direct shear test device applies a normal load on a soil-rock mass sample and applies horizontal shear force so that shear failure of the sample occurs on a proposed shear surface, and records shear stress, displacement and other related data in a test process through an automatic data acquisition system. The test device comprises a test sample (00), a shear box (10), a counter force system (20), a vertical pressure system (30), a load transfer system (40), a tangential pressure system (50), a roller row (60) and an automatic data acquisition system (70). The soil-rock mass in-situ direct shear test device disclosed by the utility model, under strain control, is high in measurement precision and good in stability; the soil-rock mass in-situ direct shear test device adopts the automatic data acquisition system, |
