Slope failures frequently cause labour accidents in construction sites, and even a small collapse can cause serious injury to workers. The Short Pipe Strain transducer (SPS) was developed to measure shear strain increments in the shallow section of slopes, and its applicability was examined through centrifuge model tests and prototype model tests. Prior to slope failure, obvious increases in the response of strain (r_s) were measured during slope cutting tests. In loam ground, creep strain curves were observed. A couple of minutes can be provided by monitoring the second or third creep. Accordingly, it was confirmed that the SPS not only measures slope movement but also senses an increase in the risk of slope failure. Slope inspections must be conducted to ensure safety during work, and the SPS is effective for subsidiary warning systems that save workers' lives.
