The characteristics of swelling stress of buffer backfilling material have been studied by forcebalance
method and constant volume test method in this paper. The constant volume test apparatus was
designed by the authors. Results show that swelling stress changing with time is a little different between the
two methods. The value of swelling stress measured by constant volume test is more accurate; besides, uptaking
water with time could also be monitored by constant volume test. The constant volume test method is more
suitable for measuring the swelling stress of buffer backfilling material.
Key words: Bentonite, swelling stress, buffer backfilling material, high-level radioactive waste, measuring, ,
