Device for automatically monitoring slope soil stress-strain

The utility model belongs to the technical field of geology monitoring, and specifically relates to a device for automatically monitoring slope soil stress-strain. The device comprises an induction unit. One end of the induction unit is connected to a data acquisition unit, and the other end is a sealing end. The induction unit comprises a flexible pipe body. The outwall of the flexible pipe body is provided with a resistor strain gauge. The data acquisition unit comprises a housing. A data collector, a power supply and a signal output unit are disposed in the housing. The data collector is connected to the signal output unit. The resistor strain gauge is connected to the data collector. The device utilizes the resistor strain gauge, is small in size and easy to measure, and enables multi-point monitoring. The device is provided with a dynamometer to directly measure the stress value that is compared with a stress value calculated by a strain value monitored by the resistor strain gauge, so that the accuracy of monitored data is ensured.
