| Abstract: | A kind of special strain-gauge with large strain capacity has been developed and applied in the measurement of tensile deformation for geotextiles. A variety of feasibility tests of tensile deformation measurement with a large capacity strain-gauge for soft material, geotextiles are presented in detail. The tests for reinforcement of soft foundation both in lab. and in field are made with the help of this kind of strain-gauge. Many key technical problems of large capacity strain-gauge applied in deformation measurement for geotextiles are found and solved through lots of tests. |
