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

Application of The New Shape Crushing Plate in Machine Crushing Processes

consumption of the technological systems of minerals processing. The technological process should also be matched to the material properties to ensure maximum effects in terms of technology, economy and ecology. The jaw crusher works on the initial stage of the crushing process (the first stage of crushing) in the raw material processing plant. In mining these crushers are used for processing ores, coal and rock materials. The most common crushers used are double toggle (such as Blake type) or single toggle jaw crusher (Dalton type). In this work, studies on Blake type

Slurry shield tunneling in soft ground. Comparison between field data and 3D numerical simulation

1 Introduction During the past decade, pressurized-face tunnel-boring machines (TBMs), such as slurry shield, have established itself as a proven technology. It is characterized by safety, excavation speed, and minimal impacts on the surrounding environment ( Xie et al., 2016 ). It is usually used in urban areas where the control of ground movements is an essential task in the design of shallow tunnels. However, shield tunneling inevitably causes some ground movements that can have adverse effects on both buried and aboveground infrastructures and buildings

Geotechnical Problems Of The Foundation Of Road Embankments By The Bridge Structures

the given value of displacements of the soil loaded with road embankment or foundation of the structure on low-strength or organic soils - it is necessary to replace the subsoil or to strengthen it. During the construction of bridge structures placed on soft soils usually is applied the reinforcement in the rigid support technology, which allows for high accuracy in settlement estimation (minimum ones, approx. 2-3 cm) - indirect foundation on piles, constrained modulus columns ( CMC ) or soil cement columns ( DSM ). The another way are consolidation techniques (in
