Characterisation and Monitoring of an Active Rock Glacier in the Swiss Alps

摘要

Field data collected over approximately one year confirm the existence of permafrost in this rock glacier. This was a first important step to achieving a combined numerical model. Two new boreholes were planned and were drilled in August 2011 more or less on the same axis and below the others. Various types of pressuremeter tests were carried out to measure the in situ response to constant strain rate and constant stress creep tests. A thermistor chain as well as an inclinometer was installed in each borehole. The field characterisation and monitoring will be supplemented with geotechnical tests in the laboratory.
