Abstract
A new rockfall protection MSE-Wall (Mechanically Stabilized Earth Wall) by the reinforcement soil fill which used geosynthetics was designed, and developed. This rockfall protection MSE-Wall is a compilation structure with high energy absorption performance. It is composed of three materials such as the impact catchment bags, the impact transmission bags, and the MSE-Wall. To check the performance of the rockfall protection MSE-Wall, the actual rolling rock test was done. In the test, boulders of 1tf-15tf weight dropped from the slope of about 40m height to the rockfall protection MSE-Wall. As a result of the test, in the case of the falling rock energy was 230tf·m, the transformation of the wall was only 9cm, and it was able to catch the falling rock in all cases. The safety of the rockfall protection MSE-Wall against a very large-scale boulder was confirmed by this actual rolling rock test.
