Please help me find the solution.

Fig. $8$ shows a cross section of a concrete gravity dam. Please check the stability of this dam against sliding, considering the water pressure in the upstream as primary loading.

Calculate the tension force in the anchor $[$in kN$]$ used to stabilize the dam against sliding for loading Fig. $8$: Cross section of concrete wallcase $1?$ The unit own weight of the concrete dam can be assumed as $/`=21/11$ kN$/$m$^3.$

Safety factors: $$G $=1\mathrm{.}35$ ; $$R$,$h $=1\mathrm{.}10$
