Is Westergaard's Hydrodynamic equation valid?
Is Westergaard's Hydrodynamic equation valid?
(OP)
Im analysing a caisson structure. the hydrodynamic force on the caisson structure obtained from the transducers installed on it is much much higher than the theoretical value given by the westergaard's equation. can anyone please tell me why people still use westergaard equation for construction at port and harbor facilities? Do they use high factor of safety to account for the actual condition?

the soil also has pore water in it. Now is there is an earthquuake, will the ocean water pressure on wall, soil pressure on wall, pore water pressure on wall be in same phase with earthquake acceleration or in opposite or some of those in same phase and some in opposite?

One question that occurred to be but I can't answer is To what extent you can take advantage of the very short duration of loading from each cycle? Can you allow for momentary yield a few tenths of a second without failure of the structure? I can't comment on the validity of Westergaard either, but I've never seen anything to replace it.

It appears that you case looks like Quaywall.
If I recall, there are few papers published in "Soils and Foundations"(Japanese journal). There may be some ASCE Special publications.

Earth pressure has a dynamic contribution as well.
