The equivalent water density overloading parameter of earthquakes.

Peak acceleration of design earthquakes	0.1 g	0.2 g	0.4 g
Static water pressure of upstream (10^7 N)	11.6
Earthquake hydrodynamic pressure (10^7 N)	0.38	0.76	1.51
Earthquake inertial force (10^7 N)	1.13	2.26	4.51
The total dynamic force/static water pressure	0.13	0.26	0.52
Overloading parameter of water density 𝐾𝑃	1.13	1.26	1.52

Notes: g is the gravitational acceleration, the normal water depth of upstream reservoir is 154 m.
