CREEP EFFECTS MODELLING FOR GROUTED ANCHORS

(STEF92 Technology, 2017-06-20, Janusz Kozubal, Marek Wyjadlowski, Dmitri Steshenko)

On the basis of the system tests of pre-stressed anchors in the anthropogenic homogeneous earthwork, valuable material has been obtained to describe the rheological features of the trench with anchors. Anchors were designed as temporary construction. Anchors were made in compacted soils with no detailed geotechnical parameters. The soil material was treated at the design stage as having a significant random distribution of mechanical and physical characteristics. This resulted in the anchor system test being the b...

OPTIMISATION OF A CONCRETE PIPE CULVERT BASED ON RELIABILITY

(STEF92 Technology, 2017-06-20, Janusz Kozubal, Roman Wroblewski)

Show more

Reliability of a concrete pipe culvert was tested under rail and embankment loads. In the finite element model soil-structure interaction and nonlinear behavior of the materials were taken into account. After a preliminary study three influential variables as random were selected for presented approach to probabilistic model, i.e. concrete strength, soil density and its modulus of elasticity. Because various concrete parameters can be easily derived from the compressive strength only this parameter was selected fo...

SOIL COLUMNS WITH REINFORCEMENT

(STEF92 Technology, 2017-06-20, Janusz Kozubal, Dmitri Steshenko, Ricardo Nascimento Flores Severo)

Show more

The paper describes and analysis loess substrate collapsing under embankment as a result of flooding. The threat of huge settlements is wide spread on large loess deposits areas especially in south part of Asia. The popular in Russian Federation and common used method developed by authors is the compaction of substrate by soil columns. It is used in a variant covered with geosynthetic as barrier and reinforcement under an embankment. Authors present results of numerical calculations in direct numerical determinist...
