Using a perturbation method, these linearized equations are solved for a composite sphere with the charge densities of the rigid core surface and of the surface layer as the small perturbation parameters. Analytical expressions for the settling velocity and electrophoretic mobility of the composite sphere in closed form have been obtained from a balance among its hydrodynamic, electrostatic, and/or gravitational forces.

The Failure model of slopes can be classified into 2 kinds, toppling model and sliding model. The force distribution of each model is analyzed in oblique coordinate system, and the equation to calculate the forces are derived. Many external forces, such as earthquake force, water pressure, bursting force, bolting force and etc., can be easily considered in these equations.

This item is a new type structure direct-acting overflow valve, which adopts dynamic pressure feedback principle. That is it adds a feedback cavity on common direct-acting overflow valve's core. When there is overfall on valve port, the hydraulic force of valve port will balance with feedback cavity's hydraulic force and spring force, so it can decrease spring's stiffness, just like adding a hydraulic spring, which works together with mechanical spring, so as to minish valve port pressure range.

The force of potential sliding body is determined using the FISH program of 3DEC based on Limited Equilibrium Method. And the sliding force and resistance force of potential sliding body are obtained by the resolution of acquired body force along the potential sliding plane. Thus the varied factor of safety of the slope under seismic loads is obtained.
