dear sir/madam,     i am designing a thrust block for 1.1m dia and when checking for stability against sliding the thrust block section is not passing. my concern is, can we design the thrust block for 50% of the thrust force and remaining 50% is taken by the longitudinal stresses in the pipe.thank you,Regards,Vishwa Hiremath9611349417

50% is not correct.


Design has to consider soil pressure resisting at the opposite side face of thrust force direction and  friction between thrust block bottom and soil and check the overall FOS against sliding to be below 1.5 minimum
