Abstract

Mehanika tla ima važnu ulogu u graditeljstvu. Bavi se analizom parametara tla koji utječu
na njegovo ponašanje, a time i mogućnost uporabe. Tlo je izrazito heterogeno te mu
svojstva ovise o mnogim čimbenicima, što ga čini prilično složenim i nezahvalnim
materijalom za ispitivanje. Unatoč tome, zbog svoje rasprostranjenosti i lakoće uporabe,
jedan je od najkorištenijih materijala.
Posmična čvrstoća tla jedan je od parametara tla koji se koristi u analizi stabilnosti tla. Za
njegovo mjerenje postoje terenske i laboratorijske te direktne i indirektne metode.
U radu je predstavljeno ispitivanje uzoraka tla laboratorijskom krilnom sondom u kojemu
je direktno dobivena vrijednost nedrenirane posmične čvrstoće. Uzorcima je ispitana i
jednoosna tlačna čvrstoća sa slobodnim bočnim širenjem. Ova metoda često se koristi za
procjenu vrijednosti nedrenirane posmične čvrstoće prema općeprihvaćenoj korelaciji sa
tlačnom čvrstoćom. Razmotrena je veza između vrijednosti dobivenih u oba ispitivanja
na dva uzorka.

Abstract (english)

Soil mechanics plays an important role in construction. It deals with the analysis of soil
parameters that affect its behavior, and thus the possibility of soil use. Soil is extremely
heterogeneous and its properties depend on many factors, making it a rather complex and
ungrateful testing material. Despite that, soil is one of the most used materials due to its
prevalence and easy usage.
Shear strength of soil is one of the soil parameters used in a soil stability analysis. There
are field and laboratory, direct and indirect methods for its measurement.
The paper presents the testing of soil samples with a laboratory vane in which the value
of undrained shear strength was directly obtained. Uniaxial compressive strength at free
lateral expansion was also tested on same samples. This method is often used to estimate
the value of undrained shear strength according to a generally accepted correlation with
compressive strength. The relationship between the values obtained in both tests on the
two samples was discussed.
