Keying Behaviors of Strip Plate Anchors with Padeye Offset in Uniform Clay
(ASCE, 2024/05/01)Plate anchors have great advantages that are useful in deep or ultradeep water mooring systems. The keying behaviors have a deep effect on the embedment loss and pullout capacity of strip plate anchors. In this paper, the ... -
Stability Evaluation Model of Large Rectangular Foundations on Soil under Combined Loading
(ASCE, 2024/06/01)The bearing capacity of large rectangular foundations on soil subjected to combined loading [simultaneously subjected to vertical load (V), overturning moment (M), and horizontal or lateral load (H)] is one of the central ... -
Comparison between Free- and Fixed-Head Pile Group Responses under Lateral Spreading in the Presence of Protection Piles Using Shake Table Tests
(ASCE, 2024/05/01)Many instances of severe damage to pile foundations and pile-supported infrastructures have been caused by liquefaction-induced lateral spreading during major earthquakes, particularly in coastal areas. The current study ... -
Modeling the Thermal-Induced Buckling of Offshore Pipelines in Clay Using the Effective Stress RITSS Method in Three Dimensions

Bearing Capacity of a Skirted Square Footing under Eccentric Loading in Granular Soil
(ASCE, 2024/05/01)The ultimate bearing capacity of a shallow footing decreases when it is subjected to a moment in addition to a centric vertical load. A centric vertical load with a moment on a footing is equivalent to an eccentric load ... -
Study on the Impact of Adjacent Horizontal Unloading on the Security Zone and Tunnel Structure of an Operating Subway
(ASCE, 2024/05/01)The construction of deep foundation pits that are adjacent to an operating subway tunnel can cause significant disturbance to the surrounding soil and tunnel structure. Assessing the stability of the soil in the security ... -
Centrifuge Model Test Study of Structuralized Cemented Slopes under Excavation Conditions
(ASCE, 2024/03/01)Excavation often results in a decrease in the stability level of natural and manmade slopes. To address this issue, a new reinforcement method––structuralized cementation––has recently been introduced to reinforce ... -
Numerical Simulation and Application Research of Straight-Hole Cut Blasting with Empty Holes in Railway Tunnels
(ASCE, 2024/04/01)An empty hole in tunnel blasting and excavation serves as an auxiliary free surface and compensation space for blasting rocks, significantly influencing the blasting effects. The straight-hole cut blasting with an empty ... -
Experimental and Numerical Investigations on the Effect of In Situ Stress and Discontinuities Orientation on the Deformation Modulus of Rock Masses
(ASCE, 2024/02/01)Deformation modulus is one of the geomechanical parameters of rock masses; it is widely used in the design and numerical modeling of rock structures. This parameter can be calculated using empirical methods and in situ ... -
Analysis of Rainfall-Caused Seepage into Underlying Bedrock Slope Based on Seepage Deformation Coupling
(ASCE, 2024/05/01)Precipitation is one of the most important factors inducing shallow slope failures, and the shallow slope covering bedrocks is prone to instability after heavy rainfall. In one-dimensional (1D) seepage–deformation coupling ... -
Seismic Response of Embankment Dams with Asphalt–Concrete Cores Based on the Three-Dimensional Time-Domain Inversion of Ground Motions
(ASCE, 2024/03/01)In this paper, the three-dimensional time-domain inversion of ground motions and its application are performed. The relationship between the incident wave time series and design ground motions is established, and the oblique ... -
Numerical Simulation of the Interaction between Hydraulic Fracture and Natural Fracture Using the Extended Peridynamic Model
(ASCE, 2024/04/01)For oil and gas exploitation engineering, it is significant to study the interaction between hydraulic fracture (HF) and natural fracture (NF). An extended peridynamic (PD) model for hydraulic fracture analysis is presented, ... -
