Abstract
In Japan, rockfall retaining walls as safety facilities of roads are designed as the
gravity type with a plain concrete structure. In this paper, in order to investigate
impact behavior of the structure, prototype impact tests are conducted by letting
a steel weight with a predetermined velocity collide. Elasto-plastic impact
analyses on the walls are also performed and an applicability of the proposed
method is discussed comparing with the experimental results. From this study,
the following results are obtained: 1) using the proposed numerical analysis
method, weight impact force wave, rotation of the wall, and crack pattern can be
precisely predicted; and 2) this analytical me
