RISAxisymmetric Consolidation in Unsaturated Soil Deposit Subjected to Time-Dependent Loadings
Publisher: American Society of Civil Engineers
Abstract: This paper presents an analytical solution to predict the axisymmetric consolidation in unsaturated soil deposits subjected to different time-dependent loadings. The mathematical procedure uses the separation of variables ...
Impact of In Situ Soil Shear-Wave Velocity Profile on the Seismic Design of Tall Buildings on End-Bearing Piles
Publisher: American Society of Civil Engineers
Abstract: In this study, a numerical investigation into how the shear wave velocity profile affects the seismic performance of tall buildings and foundations was carried out using FLAC3D software. The in situ soil profile and ...
Analytical and Numerical Approaches to Attain the Optimum Tapering Angle for Axially-Loaded Bored Piles in Sandy Soils
Publisher: ASCE
Abstract: This study aims to establish an equation to obtain the optimum tapering angle (αopt) for bored tapered piles that is correlated with pile geometry and sand properties that vary with the relative density. This αopt corresponds ...
Analytical Solution to Analyze LTP on Column-Improved Soft Soil Considering Soil Nonlinearity
Publisher: American Society of Civil Engineers
Abstract: In this paper, a mechanical model to idealize the load-settlement response of the load transfer platform (LTP) on column-improved soft soil is proposed. This model simultaneously considers the nonlinear and time-dependent ...
Development of a Constitutive Model to Predict the Behavior of Cement-Treated Clay during Cementation Degradation: C3 Model
Publisher: American Society of Civil Engineers
Abstract: Many researchers have indicated how cementation allows treated soft clays to sustain a higher yield mean effective stress at the same void ratio as its reconstituted state, and thus, the strength of clay treated with cement ...
Experimental and Numerical Investigations to Evaluate Two-Dimensional Modeling of Vertical Drain–Assisted Preloading
Publisher: American Society of Civil Engineers
Abstract: In this study, the efficiency of proposed formulations for plane-strain modeling of vertical drain–assisted consolidation was evaluated. For this aim, the vertical drain–assisted preloading process was experimentally ...
Assessment of the Elastic-Viscoplastic Behavior of Soft Soils Improved with Vertical Drains Capturing Reduced Shear Strength of a Disturbed Zone
Publisher: American Society of Civil Engineers
Abstract: Soil disturbance induced by the installation of vertical drains reduces the horizontal soil permeability and shear strength in the disturbed zone. Thus, the soil disturbance contributes to the reduced overconsolidation ...
Impacts of Drying-Wetting and Loading-Unloading Cycles on Small Strain Shear Modulus of Unsaturated Soils
Publisher: American Society of Civil Engineers
Abstract: The small strain shear modulus (Gmax) is an important parameter in geodynamic problems. To predict the Gmax of unsaturated soils that are normally subjected to complex drying and wetting processes, the effect of hydraulic ...
Interpretation of Dynamic Pile Load Testing for Open-Ended Tubular Piles Using Finite-Element Method
Publisher: ASCE
Abstract: For a foundation to perform safely, the ultimate strength of each pile must satisfy the structural and geotechnical requirements. Pile load testing is considered to be a direct method for determining the ultimate geotechnical ...
Axial and Lateral Efficiency of Tapered Pile Groups in Sand Using Mathematical and Three-Dimensional Numerical Analyses
Publisher: ASCE
Abstract: This study presents a new mathematical equation for calculating the pile group efficiency in cohesionless soil under combined axial and lateral loading conditions, considering the tapering angle effect. Based on the ...
