A Three-Dimensional Grouting Model Considering Hydromechanical Coupling Based on the Combined Finite-Discrete Element Method
(ASCE, 2022/11/01)In this paper, we present a three-dimensional (3D) grouting model based on the combined finite-discrete element method (FDEM). The 3D grouting model discretizes the problem domain into tetrahedral elements and joint elements, ... -
Study on the Coupled Mechanism of Seepage–Stress–Damage and Damage Constitutive Model of Rock after Freezing and Thawing
(ASCE, 2022/11/01)Tunnel engineering in the cold region often experiences the coupling of the stress field and seepage field, which has complex mechanical behavior and permeability characteristics. This study takes sandstone as the research ... -
Experimental and Theoretical Research on the Anisotropic Deformation and Energy Evolution Characteristics of Shale under Uniaxial Cyclic Loading and Unloading
(ASCE, 2022/11/01)Shale is often encountered during rock engineering. The inherent anisotropy of shale and the loading and unloading path affect the failure characteristics of this material. In this study, shale specimens with seven different ... -
Ultimate Bearing Capacity of Helical Piles as Electric Transmission Tower Foundations in Unsaturated Soils: Analytical, Numerical, and Experimental Investigations
(ASCE, 2022/11/01)In this paper, the compressive and tensile ultimate bearing capacity of helical piles, in the load range required for designing 63-kV transmission towers, are studied by conducting analytical and numerical investigations. ... -
Thermomechanical Behaviors of an Energy Pile–Raft Foundation under Intermittent Operation with Forced Heat Recharge
(ASCE, 2022/10/01)This paper presents an experimental investigation of the thermal and mechanical behaviors of an energy pile–raft foundation under intermittent heating operation with forced heat recharge, with 16 h of pile cooling and 8 h ... -
New Statistical Quantification Method for the Size Effect Behavior of Rock Mass Using Compressive Strength as an Example
(ASCE, 2022/11/01)The statistical law on mechanical parameters of rock mass with size is the key to the study of the size effect. Since the existing statistical methods of the size effect only consider the continuity of the size but not the ... -
A Novel Global Stress Method for the Limit-Equilibrium Analysis of Slope Stability Considering Stress Constraint Conditions at Ends
(ASCE, 2022/11/01)Slope stability analysis is an important research hotspot in geotechnical engineering. For a slope under general conditions, the tension stress zone (TSZ) is located at the rear edge and the shear stress elevated zone ... -
Formula of Passive Earth Pressure and Prediction of Tunneling-Induced Settlement in Anisotropic Ground Based on a Simple Method
(ASCE, 2022/10/01)The existence of soil anisotropy makes the strength and deformation of the ground dependent on the loading direction, which should be considered in some geotechnical engineering designs. This paper introduces the anisotropic ... -
Self CPT<i>u</i> Measurements for Determining <i>s<sub>u</sub></i> and OCR in Clay Soils: Simulation and Practical Applications
(ASCE, 2022/11/01)The undrained shear strength (su) and overconsolidation ratio (OCR) of clayey soils are two key parameters that are frequently used in geotechnical engineering practice. In comparison to laboratory tests that are expensive ... -
1D Free Swelling Model of Bentonite under Chemomechanical Coupling Action
(ASCE, 2022/11/01)Describing the time-dependent free swelling behavior of bentonite in saline solution is challenging as it is determined by the coupling effect of the chemical field and the swelling stress field in soil. The swelling ... -
Brittleness Effect on Acoustic Emission Characteristics of Rocks Based on a New Brittleness Evaluation Index
(ASCE, 2022/10/01)Brittleness has an important effect on the deformation and failure behavior of rocks. In this study, a brittleness evaluation index (Bp) based on the prepeak stress–strain curves of rock was proposed, and its effectiveness ... -
