In order to predict the arrival time and wave height of the shock wave (surge) from a landslide source to the hazard-affected body, the near-field wave characteristics of the surge induced by the reservoir rock mass landslide were experimentally studied. Firstly, according to the typical rockslide parameters and rock fracture characteristics in the Three Gorges reservoir area, a three-dimensional physical laboratory model for cracked rockslide generated impulse waves was built based on the generalized Froude similarity. Then, the near-field wave generation mechanism and propagation law were revealed though model tests. Finally, a prediction model of near-field waves was established by multiple regression analysis. The results showed that the main driving force of the first wave is the displacement and drag of the landslide to the water body; the size of the leading wave trough amplitude depends on the duration of the water collapse. According to the underwater movement process of the landslide, two critical water depths are introduced in this paper, and the calculation method of the first wave trough generation time is proposed. Furthermore, the first wave crest propagates at velocities up to the approximate solitary wave celerity. The celerity of the first wave trough and the second wave is lower than that of the solitary wave, and their measureless phase wave speeds are 0.9, 0.78 and 0.68 times the solitary wave celerity, respectively.
