Abstract: In western region of China, there are numerous alpine valleys. The special topography develops a large numbers of mountain disasters of rock-fall. It badly threatens the safety of people. Generally, the shed is the most effective engineering method. However, the impact behavior of rock shed is a complicated dynamic process, especially in the aspect of contact response between slab and rock-fall. The application of rock-fall shed is seriously restricted because of the current research status. In view of the present disadvantages of Herzt contact law, a theoretical method of dynamic response of reinforced concrete (RC) slab is proposed based on the numerical indentation test and the Olsson’s model. Compared to the presented methods, the results obtained in this paper are much closer to the results of finite element method. Meanwhile, the impact forces obtained by Herzt model are larger because of without considering of plastic deformation. As a much reasonable method, it can be used to analyze the dynamic response of RC slabs subjected to impact load of rock-fall. At the same time, it also provides an effective numerical analysis method for the application of
indentation test to civil engineering.
