KON.007 - Geotechnics

The standard comprises requirements for ground investigations by means of the field vane test (FVT) as part of the geotechnical investigations.

This standard forms part 4 of the series ISO 18674, as described in ISO 18674-1: Part 1. General rules the methods and gives rules for measurement of pore water pressures in geotechnical engineering or more general in foundation engineering. Pore pressures are needed to obtain effective stresses and play a key role in the analysis of engineered construction in and on ground.

The standard comprises requirements for ground investigations by means of the borehole dynamic probing (BDP) as part of the geotechnical investigations

This standard forms part 5 of the series ISO 18674, as described in ISO 18674-1: Part 1. General rules the methods and gives rules for measurement of total stresses  in geotechnical engineering or more general in foundation engineering. Stresses in soil or rock  are needed to judge the loading of engineered construction in the ground.

All types of piles are covered by this standard.
The tests considered in this Standard are limited to maintained load tests.
EN 22477-1 shall be used in conjunction with EN 1997-1. Numerical values of parti...view more

Tests with the full displacement pressuremeter cover the measurement in situ of the deformation of soils and weak rocks by the expansion/contraction of a cylindrical flexible membrane under pressure.
The FDP is jacked into the ground with an integral cone at its ...view more

This Standard establishes specifications for the execution of tension tests to be carried out on an anchor grouted in the ground, as defined in EN 1997-1 and EN 1537. Three methods of test are recognised by this Standard. Method 1 involves cyclic tension loading with measurement of displacement at the load stages. Method 2 involves cyclic tension loading with measurement of loss of load after lock-off at peak load and Method 3 involves step-loading with measurement of displacement under successi...view more

This document specifies methods for the determination of the liquid and plastic limits of a soil. These
comprise two of the Atterberg limits for soils.
The liquid limit is the water content at which a soil changes from the liquid to the plastic state.
This document describes the determination of the liquid limit of a specimen of natural soil, or of
a specimen of soil from which material larger than about 0,4 mm has been removed. This document
describes two methods: the fall cone method and ...view more

This document specifies a method for consolidated triaxial compression tests on water-saturated soils.
This document is applicable to the laboratory determination of triaxial shear strength under
compression loading within the scope of geotechnical investigations.
The cylindrical specimen, which can comprise undisturbed, re-compacted, remoulded or reconstituted
soil, is subjected to an isotropic or an anisotropic stress under drained conditions and thereafter is
sheared under undrained or d...view more

This document specifies a method for unconsolidated undrained triaxial compression tests.
This document is applicable to the laboratory determination of undrained triaxial shear strength under
compression loading within the scope of geotechnical investigations.
The cylindrical specimen, which can comprise undisturbed, re-compacted, remoulded or reconstituted
soil, is subjected to an isotropic stress under undrained conditions and thereafter is sheared
under undrained conditions. The test al...view more

This standard establishes the specifications for the execution of dynamic pile load tests in which a single pile is subject to an axial short duration impact load in compression to predict its ultimate compressive resistance and load-displacement behaviour including shaft friction distribution and toe resistance.

This document specifies the basic principles for classification of those material characteristics
most commonly used for soils for engineering purposes. It is intended to be read in conjunction
with ISO 14688-1, which gives rules for the identification and description of soils. The relevant
characteristics could vary and therefore, for particular projects or materials, more detailed subdivisions
of the descriptive and classification terms could be appropriate. Due to differences in local geo...view more

This document specifies a method for the unconfined compression test.
This document is applicable to the determination of the unconfined compressive strength for a
homogeneous specimen of undisturbed, re-compacted, remoulded or reconstituted soil under
compression loading within the scope of geotechnical investigations.
This test method is useful to estimate the undrained shear strength of soil. It is noted that drainage
is not prevented during this test. The estimated value for undrained s...view more
