Probabilistic Analysis of Step-Shaped Slopes Using Random Field Models
(ASCE, 1/1/2020 1)Step-shaped slopes are often found in mines. The reliability of step-shaped slopes was investigated based on random field models. The factor of safety of slopes was derived by the horizontal and vertical integration methods. ... -
Large-Scale True Triaxial Test on Stress-Strain and Strength Properties of Rockfill
(ASCE, 1/1/2020 1)Limited by the particle size requirements of testing apparatus, little true triaxial test (TTT) research on rockfill has been conducted. Using a large true triaxial apparatus (TTA) developed independently by the Changjiang ... -
Load Transfer Mechanisms of Granular Cushion between Column Foundation and Rigid Raft
(ASCE, 1/1/2020 1)The granular cushion has been increasingly used as a load transfer platform between a column foundation and a raft to ensure appropriate contact and load transfer among the raft, the columns, and the soil. However, deformation ... -
Modeling of Vehicle-Track-Tunnel-Soil System Considering the Dynamic Interaction between Twin Tunnels in a Poroelastic Half-Space
(ASCE, 1/1/2020 1)The vibration prediction of a vehicle-track-tunnel-soil dynamic system is quite meaningful in engineering practice. However, the complexity involved in modeling the underground environment makes most previous studies ignore ... -
Experimental and Numerical Investigations on Confined Granular Systems Stabilized by Bacterial Cementation
(ASCE, 1/1/2021)Bacterial cementation is a relatively new technology for stabilization of granular systems where cementation happens incrementally with repeated injection of the cementation fluid through the pores of the granular media. ... -
Horizontal Displacement of Urban Deep Excavated Walls Supported by Multistrands Anchors, Steel Piles, and In Situ Concrete Piles: Case Study
(ASCE, 1/1/2021)Deep excavations are commonly used in urban areas due to the extreme increase in ground worth. Stability and displacement of adjacent structures are two main design criteria in stabilized excavated walls. In this paper, ... -
Real-Time Updated Risk Assessment Model for the Large Deformation of the Soft Rock Tunnel
(ASCE, 1/1/2021)Large deformation of the surrounding rock is a common geological hazard when excavating a new tunnel to be driven through soft rock, and this occurrence can severely interrupt the construction schedule and affect the safety ... -
Retracted: Experimental Study on the Settlement Properties of Silt Containing Fine Particles after Liquefaction: Case of Xiong’an New Area of China
(ASCE, 1/1/2021)The site earthquake often causes serious soil liquefaction, especially results in volume change and surface subsidence to cause many secondary disasters. Different from the previous research on volume strain settlement of ... -
Investigation of Development of the Earth Pressure Coefficient at Rest in Clay During Creep in the Framework of Hyper-Viscoplasticity
(ASCE, 1/1/2021)The in situ earth pressure coefficient at rest (K0) for clay has been widely discussed in the literature. In engineering practice, the empirical relationships between K0, the overconsolidation ratio (OCR), and the normally ... -
Experimental Investigation of Mechanical Properties of Ballast Contaminated with Wet Sand Materials
(ASCE, 1/1/2021)Considerable parts of worldwide railway networks cross deserts where there are frequent sandstorms, which cause contamination of ballast. One of the most important challenges for railway industries is the adverse effects ... -
Stability of Unlined Rectangular Tunnels in Rock Masses Subjected to Surcharge Loading
(ASCE, 1/1/2021)This paper investigates the stability of unlined rectangular tunnels in rock masses subjected to surcharge loading using adaptive finite element limit analysis based on the generalized Hoek-Brown failure criterion. Both ... -
Response and Stability of Piles Subjected to Excavation Loading
(ASCE, 1/1/2021)This paper develops new models and normalized solutions to capture the response of piles subjected to a mixed translation–rotational soil movement. A flexible pile is divided into upper and lower portions, which join ... -
Interpretation of Japanese Wood Building Damage Based on Soil–Foundation Connection Modeling
(ASCE, 1/1/2021)Japanese wood building damage was concentrated on the first story of buildings in previous large earthquakes. The main reason was attributed to an undesirable layout (lack of shear walls) in the first story. However, it ... -
Vertical Vibration Analysis of a Pile Group in Multilayered Poroelastic Soils with Compressible Constituents
(ASCE, 1/1/2021)This paper will investigate the vertical vibration of a pile group connected to a rigid cap in multilayered poroelastic soils with compressible constituents. Individual piles in the pile group are modeled as one-dimensional ... -
Laboratory Study on Diffusion and Migration of Grout in Rock Mass Fracture Network
(ASCE, 1/1/2021)The flow process of grout in a rock mass fracture network is an important part to judge the effect of grouting in engineering. Till date, little research has been done on the diffusion and migration pattern of grout in a ... -
Seismic Slope Stability Analysis of a Hydraulic Fill Dam
(ASCE, 1/1/2021)This paper presents a seismic slope stability assessment study of an inherently heterogeneous hydraulic fill dam in Texas. Extensive cone penetration soundings conducted at the dam site were interpreted to estimate different ... -
Consolidation Considering Clogging Effect under Uneven Strain Assumption
(ASCE, 1/1/2021)In land reclamation projects, the vacuum preloading method has been widely used to strengthen dredged fills by removing water. However, during the improvement process, clogging inevitably occurs in the drains and soils, ... -
