Large-scale load tests comprised recording of the creep strain rate that was found to be strongly retarded and negligible for stresses lower than about 1/3 of the failure load. For higher stresses creep took place according to a log time law representing secondary creep that ultimately changed to tertiary creep and failure. }, journal = {International Journal of Geotechnical and Geological Engineering}, volume = {6}, number = {8}, year = {2012}, pages = {1577 - 1582}, ee = {https://publications.waset.org/pdf/1445}, url = {https://publications.waset.org/vol/68}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 68, 2012}, }
