Pressumeter test
Pressumeter test
(OP)
Hello
i would like ask you about computing bearing capacity for shallow foundations using the Pressumeter Test .No need to say that we conduct the test for initial soil conditions, but usually the exact same soil is wetted upon unloading . This could have a great deal of effect on comprehensibility and softening of the soil especially if the soil was initially dry ( i.e clays) , so is it reasonable to say that the bearing capacity will decrease afterwards ?
What about the case of removing an important amount of overburden pressure for ex in clayey soils ? i assume this will release the stresses above the clay and subsequent softening will occur ,so that the limit pressure will change somehow am i right ?

But i was thinking that softening of OC clays and opening of fissures can alter the structure of the soil ( bare in mind i am talking about 12 m of soil getting removed ).
Could you please answer the first question ?
