Design Manual Engineering Properties of Soil and Rock
Soil is a nonhomogeneous, porous material for which engineering behavior is greatly influenced by density, source material, stress history, and hydrogeology. Some engineering properties (e.g., undrained shear strength in normally consolidated clays) may vary as a predictable function of a stratum dimension (e.g., depth below the top of the ...

Deformation analysis of deep foundation pit excavation in ...
The excavation of a deep foundation pit often causes deformation, so it is of great value to analyse the issue. In this study, the space–time effect of foundation pit deformation was introduced, and then the deformation of a deep foundation pit in Anyang, China, was monitored and analysed. The results showed that the displacement of the foundation pit enclosure structure increased gradually ...

Three‐dimensional hydromechanical modeling of internal ...
This paper presents a three-dimensional (3D) numerical simulation of the effects of internal erosion within a linear dike located on a foundation. A two-dimensional (2D) finite element code has been extended to 3D in order to analyze the impact of internal erosion under more realistic hydromechanical conditions.

Behavior of Monopile Foundations for Offshore Wind Farms ...
Most offshore wind-turbine foundations are monopile foundations. Monopile foundations have the advantages of simple structures and are convenient to construct. In recent years, large-diameter monopile foundations, with diameters larger than 4 m, have been used in engineering applications to increase the bearing capacity of wind turbines.

The influence of the inherent fabric anisotropy of sand and its evolution on the footing bearing capacity and failure mechanism has been modelled and analysed with a multiscale approach that couples the finite-element method (FEM) and the discrete-element method (DEM). In this approach, the material constitutive responses are captured by DEM simulations on representative volume elements …

The last layer above the high stiffness weathered rock is clayey sand or a mixture of sand, gravels and clays. The clayey sand layer is about 3m thick. The weathered rock is found at the level of 30m.
