Effective Friction Angle Of Deltaic Soils In The Vistula Marshlands

1 Introduction 1.1 Aim of research This research is focused on effective angle of internal friction and compares the results for the Vistula Marshlands muds and peats with similar soft soils. Effective shear strength parameters of the deltaic soils near Gdańsk are measured in drained and undrained triaxial compression tests and estimated with the Norwegian Institute of Technology (NTH) method using the Cone Penetration Tests (CPTU) sounding. The observed dilative-contractive soil behaviour is discussed taking into account the CPTU classification chart

Effect of randomly distributed polypropylene fiber reinforcement on the shear behavior of sandy soil

, 23 ] Experimental results from various tests (direct shear, unconfined compression and triaxial compression) have confirmed that the efficiency of fiber treatment is highly dependent on the fiber concentration, on testing conditions (e.g., stress and strain levels, stress path and loading direction) and on a large number of variables related equally to the physical and dimensional characteristics of both fiber and sand matrix (e.g.,fiber and particle sizes and particle size distribution, particle shape and fiber surface, fiber/grain frictional properties

Shear strength of compacted Chlef sand: effect of water content, fines content and others parameters

a particular manner ([ 39 ], [ 40 ]). However, many researchers have mentioned that the physical nature of silty sand is entirely different from clean sand ([ 2 ], [ 26 ], [ 33 ], [ 34 ], [ 38 ], [ 41 ], [ 42 ], [ 43 ]). They have recognized that the undrained shear strength ( Sus ) response depends effectively on the void ratio as a state parameter. It is also anticipated that the global void ratio (e) cannot represent the amount of particle contacts in the sand-silt soil sample mixture. As the void ratio and the proportion of coarse-grained and fine-grained soil
