Parametric Study of Twin Tunneling Effects on Piled Foundations in Stiff Clay: 3D Finite-Element Approach
(ASCE, 2022-6-1)Due to urbanization, development of society, and growth of population, there are new demands for tunneling technique to facilitate the public transport as well as high-rise buildings to accommodate an increasing population. ... -
A Study of the Failure Mechanism of Braced Excavations Using 3D Finite-Element Analysis
(ASCE, 2022-7-1)This study aims to investigate the failure mechanism of structural support systems in braced excavations. The three-dimensional finite-element method (FEM) was used to model the complexity of real geometry by considering ... -
Modeling of Compaction Grouting Considering the Soil Unloading Effect
(ASCE, 2022-6-1)Previous studies have given little consideration to the influence of the soil unloading effect on compaction grouting. The theoretical relationship model between the soil unloading degree and the soil deformation modulus ... -
Compression and Deformation Characteristics of Hydrate-Bearing Sediments under High Effective Confining Pressure
(ASCE, 2022-6-1)The depressurization method that is used to produce methane gas can increase the effective stress in hydrate-bearing sediments and induce deformation and settlement of reservoirs, which has adverse effects on safe and ... -
A Method for Nonlinear Analysis of Raft Resting on Multilayered Heterogeneous Soils
(ASCE, 2022-6-1)This paper presents a new method for the nonlinear analysis of rafts resting on multilayered heterogeneous soils using the Vlasov model. The finite-element and the finite-difference methods are employed to solve the governing ... -
Earth Pressure Estimation of Undrained Soil–Wall Systems with Head Rotation
(ASCE, 2022-6-1)Semianalytical or analytical models for calculating active and passive earth pressure coefficients for undrained soil–wall systems subjected to head rotation are rare. To fill this gap, this study proposes a semianalytical ... -
TBM Tunnel Surrounding Rock Classification Method and Real-Time Identification Model Based on Tunneling Performance
(ASCE, 2022-6-1)The classification and real-time identification of surrounding rock grades are of great significance to guide tunnel boring machine (TBM) construction. Taking a water diversion project in China as the background, this study ... -
In Situ Stress Field along the Axis of Deeply Buried Tunnel in Southwest China Employing the Segmented Single-Borehole Inversion Method
(ASCE, 2022-6-1)Investigating the in situ stress field is one of the primary tasks of the tunnel disaster prevention and design stage in a high geostress environment with a strength–stress ratio lower than four. Due to the limited measured ... -
Experimental Investigations on the Mechanical and Microscopic Behavior of Cement-Treated Clay Modified by Nano-MgO and Fibers
(ASCE, 2022-6-1)Cement is often used to stabilize soft clay; however, it has some limitations in increasing clay strength and improving clay failure mode. To solve this, two different additives, i.e., polypropylene fiber and nano-Magnesium ... -
Effect of Design Parameters on Piled Rafts in Sand under Eccentric Triangular Loads
(ASCE, 2022-6-1)Piled raft foundations (PRFs) below stepped high-rise towers are often subjected to nonuniform triangular-shaped loads with eccentricities. In this study, 20 rectangular piled rafts with different pile configurations and ... -
Study on the Anisotropic Shear Strength of Rough Joint via 3D Scanning, 3D Printing, and 3D Discrete-Element Modeling
