Experimental and Theoretical Investigations on Active Earth Pressure Distributions behind Rigid Retaining Walls with Narrow Backfill under a Translational Mode
(ASCE, 10/1/2020 )The existing earth pressure theories, such as Rankine's theory and Coulomb's theory, adopt planar slip surfaces to establish force equilibrium equations. For retaining walls, especially for those with narrow backfill, the ... -
Allowable Displacement of Slope Supported by Frame Structure with Anchors under Earthquake
(ASCE, 10/1/2020 )Under the action of an earthquake, a slope can dissipate energy by generating a certain displacement. The critical permanent displacement in the state of limit equilibrium is the allowable displacement of the slope to ... -
Compressibility and Microstructure Evolution of Different Reconstituted Clays during 1D Compression
(ASCE, 10/1/2020 )The compressibility and microstructural changes of four types of reconstituted clays, Tianjin, Shanghai, kaolin, and montmorillonite clays, were studied to investigate the effects of mineral composition and clay content ... -
Durability of Rammed Earth Materials
(ASCE, 11/1/2020 )Rammed earth (RE) is a low-embodied-energy construction technique that attracted the attention of engineers in recent years. To date, few studies have investigated the chemical deterioration of RE. This study investigated ... -
Correlation of Geomechanical and Dynamic Elastic Properties with the P-Wave Velocity of Lower Gondwana Coal Measure Rocks of India
(ASCE, 10/1/2020 )Ground behavior during surface and subsurface coal mining activity is primarily governed by the geomechanical and elastic properties of the encountered rocks. A quick estimation of these parameters would provide an advantage ... -
Stress Intensity Factor of Dynamic Crack in Double-Layered Dry Sandy Elastic Medium due to Shear Wave under Different Loading Conditions
(ASCE, 11/1/2020 )This study deals with the deduction of the stress intensity factor (SIF) for the propagation of rectilinear semi-infinite noncentrally located interfacial crack influenced by propagating SH-waves in the framework of two ... -
Water Saturation Effects on Mechanical and Fracture Behavior of Marble
(ASCE, 10/1/2020 )Water has a significant influence on rock mechanical and fracture behavior in geologic engineering. This study investigates the water weakening effects on mechanical properties, as well as the microscopic failure, of hard ... -
Seismic Bearing Capacity of Rough Strip Footing Placed Over Geogrid-Reinforced Two-Layer Sands
(ASCE, 10/1/2020 )The lower bound limit theorem in conjunction with finite elements is used to quantitatively estimate the pseudostatic bearing capacity of a rough strip footing placed on geogrid-reinforced sandy soil. The objective of this ... -
Time Effect of Buoyant Force Reduction for Underground Structures in Clays: Model Test and Case Study
(ASCE, 10/1/2020 )Underground structures experience transient and sustained hydrostatic uplift forces throughout their service life. Conventionally, Archimedes’ principle is used to conduct uplift design. The estimated buoyant force is often ... -
Ground Reaction Curve for Deep Circular Tunnels in Strain-Softening Mohr–Coulomb Rock Masses Considering the Damaged Zone
(ASCE, 10/1/2020 )The drill and blast method is one of the most widely used techniques for excavation of tunnels in rock masses. The most worrying issue in this method is unfavorable damage induced by blast impact into the surrounding rock ... -
Two-Phase Approach for the Analysis of Laterally Loaded Pile Groups in Sandy Soils
