Zginanie jako metoda oceny wytrzymałości gruntów litych i spoistych zwartych

SUMMARY

!Due

to

the heterogeneity of the intensity of stress

the bendl!lg testB

ue

:rarely used ilnthe examina-tions of soil strength; nevertheless they can be

im-portant dJn the determiJnation. Of the strength parame-ters of soils ('both oompa'ct .and coherent, l.n the

com-pact, semi-comcom-pact, and paf'Uy haf'd.,plastic states).

The method worked out allows us

to

dete:r'miiIle:

- value Of relation between reversible

delforma-. tdons and ultimate ones (a);

- va'loo of brea:lcing strai·ns {tensional straLns Rf'); - value of ela&tie~ty modulus and deformation modulus under oondritions of various degree of load .(iFB and Ec).
