Revisiting the Fundamental Concepts of Soil Mechanics Using the General Effective Stress Concept for Saturated Geomaterials
(American Society of Civil Engineers, 2023/01/01)This paper presents a work to define four fundamental concepts, namely, buoyant force, submerged unit weight, seepage force, and critical hydraulic gradients, for saturated geomaterials including soils, rocks, and concrete ... -
Suffusion of Gap-Graded Soil with Realistically Shaped Coarse Grains: A DEM–DFM Numerical Study
(American Society of Civil Engineers, 2023/01/01)Suffusion refers to the phenomenon in which fine particles in internal unstable soil are carried by seepage through skeleton pores. It is a type of internal erosion that can lead to major hazards for hydraulic and geotechnical ... -
Three-Dimensional Stability of Slopes under Water Drawdown Conditions
(American Society of Civil Engineers, 2023/01/01)In practical engineering, slopes near reservoirs are susceptible to collapse during the rising and falling of water levels, resulting in huge financial losses. Three-dimensional (3D) upper-bound analysis is an effective ... -
The Microscopic Pore Structure Change and Its Correction with the Macroscopic Physicomechanical Properties of Sandstones after Freeze–Thaw Cycles
(American Society of Civil Engineers, 2023/01/01)Freeze–thaw damage of rocks causes many engineering problems in cold regions. During the cyclic freeze–thaw process, the frost-heaving pressure, which is produced by 9% volumetric expansion of pore water, will drive the ... -
Behavior of Saturated Remolded Loess Subjected to Coupled Change of the Magnitude and Direction of Principal Stress
(American Society of Civil Engineers, 2023/01/01)Undrained torsional shear tests were carried out on remolded loess specimens using a hollow cylinder apparatus to investigate the deformation behavior and noncoaxiality (where the direction of the plastic strain increment ... -
Large-Strain Elastic Viscoplastic Consolidation of Vertical Drains with Non-Darcian Flow Incorporating Well Resistance and Smear Zone
(American Society of Civil Engineers, 2023/01/01)Vertical drains improve the consolidation of soft clay, characterized by the large void ratio, high compressibility, and high water content, but the consolidation theory still needs to be improved. This paper investigated ... -
Experimental Study and Mathematical Description of Gradation Effect on the Mechanical Characteristics of Crushed Waste Rocks
(American Society of Civil Engineers, 2023/02/01)Crushed waste rocks, generated from mining operations, have been widely used for mining infrastructure constructions such as haul roads because of their low cost, high strength, and availability. Crushed waste rock gradation ... -
Optimum Design of Unsaturated Finite Clayey Slopes Using Second-Order Reliability Method
(American Society of Civil Engineers, 2023/02/01)This paper discusses the second-order reliability-based design optimization (SORBDO) of unsaturated finite slopes. An efficient search algorithm is proposed to locate the most probable slip surfaces using the Morgenstern–Price ... -
Shaking Table Test on Mitigation of Liquefaction-Induced Tunnel Uplift by Helical Pile
(American Society of Civil Engineers, 2023/01/01)The tunnels located in the shallow depths of loose saturated sand are significantly prone to liquefaction-induced uplift. Research works are, therefore, in progress to propose efficient techniques for mitigating uplift. ... -
Modifying Sadov’s Empirical Formula for Group-Hole Blasting in Open-Pit Mine Conditions
(American Society of Civil Engineers, 2023/01/01)Sadov’s formula is widely used to solve the seismic wave velocity problem of single-hole blasting in calculations in blasting engineering. There is a significant difference between the calculated results for group-hole ... -
A Novel Energy-Based Method to Evaluate Layered Rock Brittleness
(American Society of Civil Engineers, 2023/01/01)Rock brittleness plays an important role in rock engineering, thus it is practically valuable to assess rock brittleness accurately. Many brittleness indices have been developed, but few methods are developed for layered ... -
A Simplified Method for One-Dimensional Consolidation of Unsaturated Soils
(American Society of Civil Engineers, 2023/01/01)A simplified analytical method is proposed for one-dimensional unsaturated soil consolidation theory. First, in the one-dimensional compression test of unsaturated soil, the effective stress principle of saturated soil ... -
Nonisothermal Failure Envelopes of Strip Shallow Foundations Resting on Partially Saturated Clay Subjected to Combined Inclined and Eccentric Loadings
(American Society of Civil Engineers, 2023/01/01)Shallow foundations are commonly resting on partially saturated soil and are very likely to be exposed to severe variations of temperature. The degree of saturation and matric suction will be changed at the elevated ... -
Characterization of Wall Deflection and Ground Settlement for Irregular-Shaped Excavations with Changes in Corner Configuration
