thanks for reply, sorry about that. I'm referring to the one for uniform lateral soil pressure distribution in a braced excavation. .65*ka*gamma*H. Thanks again.
hi,
how do I use T&P emperical equation when there are different soils within the trench, say a sand on top of a clay. Also, water table is halfway down, and will be dewatered, so I'll have water pressure on bottom half of braced excavation.
Thanks
