Three-Dimensional Creep Constitutive Model of Transversely Isotropic Rock
(ASCE, 8/1/2021)Transversely isotropic rock is a typical anisotropic rock type. The existing creep constitutive models for isotropic rock do not fully reflect the creep mechanical properties of transversely isotropic rock. By considering ... -
Application of a Simplified Anisotropic Constitutive Model for Soft Structured Clay on Embankment Failure
(ASCE, 8/1/2021)The design and maintenance of embankments is still a challenge in practical geotechnical engineering because of some features of soft sensitive soil behavior that are not considered in conventional methods. These features ... -
Stochastic Analysis for Bearing Capacity Determination of Shallow Foundations on Thin-Tilted Anisotropic Soils
(ASCE, 8/1/2021)The soil stratum is heterogeneous and may be tilted with significant influence on the footing bearing capacity (BC). In this paper, a combination of influence of the anisotropy orientation and thickness of soil layer and ... -
Macro- and Micromechanical Behaviors and Energy Variation of Sandstone under Different Unloading Stress Paths with DEM
(ASCE, 8/1/2021)Various mechanical responses of rocks under a complex stress state have attracted the attention of engineers. A hollow cylinder torsional apparatus (HCA) was constructed using the discrete element method (DEM). A series ... -
Experimental and Analytical Study on Geomechanical Behavior of Biocemented Sand
(ASCE, 8/1/2021)Research on soil biocementation has gained momentum given its advantages over ordinary Portland cement-based techniques that entail a negative environmental impact. Soil biocementation occurs when bacteria-induced urea ... -
Calculation Method for Displacement-Dependent Earth Pressure on a Rigid Wall Rotating Around Its Base
(ASCE, 8/1/2021)For the displacement-dependent earth pressure on a rigid wall that rotates around its base, an analysis approach will be established based on the Duncan–Chang stress–strain model, log-spiral potential slip surface in the ... -
Lower-Bound Seismic Bearing Capacity of a Strip Footing Adjacent to an Existing Footing on Sand
(ASCE, 8/1/2021)The ideal notion of footings placed in isolation is rarely implemented in practice and footings are often placed adjacent to each other, interfering with one another's performance. In this paper, the lower-bound finite-element ... -
Effects of Undercrossing Tunneling on Existing Shield Tunnels
(ASCE, 8/1/2021)The lining rings of a shield tunnel are connected by steel bolts, which play an important role in longitudinal structural deformation during long-term operation. In recent decades, there have been increasing numbers of ... -
Axial Pullout Behavior of Buried Medium-Density Polyethylene Gas Distribution Pipes
(ASCE, 7/1/2021)This paper presents an experimental investigation into the axial pullout behavior of buried medium-density polyethylene (MDPE) pipes under various pulling rates. Tests were conducted in a facility developed at the Memorial ... -
Shear Behavior of Soil–Rock Mixture Composed of Diorite-Porphyrite Considering Weathering Sequence
(ASCE, 7/1/2021)Due to the weathering process, diorite-porphyrite dikes break up into a soil–rock mixture (SRM), which is crucial to the stability of dams and reservoirs that are under frequent fluctuations of water level. However, the ... -
Empirical Model for Shear Strength of Artificial Rock Containing a Single Nonpersistent Joint
(ASCE, 8/1/2021)This paper proposes an empirical equation to evaluate the shear strength of rock mass with nonpersistent joints. A novel specimen preparation method is proposed and is used to created plaster specimens containing nonpersistent ... -
Analytical Approach for Evaluating the Dynamic Self-Bearing Capacity of Tunnels
(ASCE, 8/1/2021)The self-bearing capacity of tunnels possesses a dynamic evolution process. However, there is a limited advanced knowledge to evaluate the dynamic self-bearing capacity of tunnels quantitatively. In this paper, the ... -
Strength Properties of Cement-Stabilized Dredged Sludge Incorporating Nano-SiO<sub>2</sub> and Straw Fiber
(ASCE, 7/1/2021)This study investigates the compressive and tensile strength properties of cement-stabilized dredged sludge (CDS) improved by straw fiber (SF) and nano-SiO2 (NS). The influence factors, including SF content, NS content, ... -
Ultimate Bearing Capacity of Rigid Footing on Two-Layered Soils of Sand–Clay
(ASCE, 7/1/2021)This study widely investigates the ultimate bearing capacity of a rigid footing on the free surface of sand overlying clay using the rigid-plastic finite-element method (RPFEM). Interface elements were introduced with the ... -
New Simple Breakage Index for Crushable Granular Soils
(ASCE, 8/1/2021)Degradation of geomaterials, that is, particle breakage, can be harmful to the full life-cycle stability of practical engineering; for example, rockfill dam, energy-pile foundation, railway embankment, and retaining wall. ... -
