The earth thrust will therefore be in the proportion 17l/lUl to the 

 force calculated for an unsaturated fill, and will be applied at a 

 height of 7,8U feet above the base. On r esolving the thrust into 

 horizontal and vertical components, the forces and moments about B may 

 be tabulated,

283. Uplift Forces and Moments . - Uplift may be calculated for con- 

 servative conditions by assuming the water level at the toe to be at the 

 base. Then the uplift force diagram is triangular and the thrust and 

 moment about B is given in Table 2$.
