  • A shaking table model experiment was designed to study the hydrodynamic pressures of the barrier lake under the action of an earthquake and a clastic flow landslide. Firstly, an experiment was carried to study the hydrodynamic pressure of the barrier lake under the action of an earthquake to obtain the hydrodynamic pressure data, which was compared with the existing calculation formula of seismic hydrodynamic pressure. Then, an experiment was carried to study the hydrodynamic pressure caused by the surge of the barrier lake under the action of a clastic flow landslide to obtain the hydrodynamic pressure data and a statistical formula was established. Finally, an experiment was carried to study the combined hydrodynamic pressure under the effect of an earthquake and a co-seismic clastic flow landslide and a formula for calculating the combined hydrodynamic pressure caused by an earthquake and a clastic flow landslide was established. The results show that the relationship between the hydrodynamic pressure caused by an earthquake and water depth and seismic peak acceleration can be described by Westergaard’ formula. The hydrodynamic pressure caused by a clastic flow landslide is negatively related to the initial water depth, positively related to the inflow velocity and volume of landslide. The combined hydrodynamic pressure is less than the sum of the single hydrodynamic pressure under the action of an earthquake and the single hydrodynamic pressure under the action of a clastic flow landslide, which is about 51% − 95% of the sum of two.
