Micro-Mesoscopic Creep Damage Evolution and Failure Mechanism of Sandy Mudstone
(ASCE, 3/1/2021)A typical sandy mudstone from the deep-buried roadway of the Kouzidong coal mine was taken as the research object. Based on the micro-mesoscopic experiments combining the acoustic emission (AE) and digital speckle correlation ... -
Performance Tests on Pressure-Dispersed Compression Anchors in Cohesive Soils
(ASCE, 3/1/2021)Pressure-dispersed compression anchor consists of several anchor units fitted with an end plate. Limited field tests have been conducted to investigate the performance of a pressure-dispersed compression anchor system in ... -
Slope Stability Analysis Considering Different Contributions of Shear Strength Parameters
(ASCE, 3/1/2021)From the perspective of the mechanical mechanism of slope failure, cohesion c usually plays a different role with friction φ in sliding resistance, which indicates the distinct weights of their reduction factors Fsc and ... -
Pullout Behavior of Triaxial Geogrid Embedded in a Transparent Soil
(ASCE, 3/1/2021)Geogrids with triangular apertures are increasingly being used as a reinforcement element in various geotechnical structures because of their characteristics to offer uniform resistance in all directions. In the present ... -
Quantitative Acoustic Emissions Source Mechanisms Analysis of Soft and Competent Rocks through Micromechanics-Seismicity Coupled Modeling
(ASCE, 3/1/2021)This research studied seismic source mechanisms of acoustic emission (AE) events generated during the failure of intact and jointed rock samples using a microscale mechanical-seismicity coupled microscale model. During ... -
Reliability Analysis of 3D Rockfill Dam Slope Stability Based on the Copula Function
(ASCE, 3/1/2021)The evaluation of slope stability reliability under the condition of incomplete probability information is one of the most popular issues in geotechnical engineering. The key difficulty in the issue lies in how to effectively ... -
Phase Field Characterization of Rock Fractures in Brazilian Splitting Test Specimens Containing Voids and Inclusions
(ASCE, 3/1/2021)The Brazilian splitting test is a broadly adopted testing procedure for characterizing the tensile strength of natural rock or rock-like material. However, the results of the Brazilian test on specimens with naturally ... -
Pile Groups Subjected to Axial and Torsional Loads in Flow-Controlled Geomaterial
(ASCE, 3/1/2021)The pile groups were used as a foundation for complex structures experiencing large axial, lateral, and torsional loads. As a result, they undergo vertical, lateral, and eccentric movements. Moreover, there were several ... -
Analytical Quantification of Ultimate Resistance for Sand Flowing Horizontally around Monopile: New p-y Curve Formulation
(ASCE, 3/1/2021)Driven by the need to enhance the performances of the Winkler model when dealing with large-diameter monopiles, the primary objective of this paper is to propose a new p-y formulation that has the ability to realistically ... -
Limit Analysis of Modified Pseudodynamic Lateral Earth Pressure in Anisotropic Frictional Medium Using Finite-Element and Second-Order Cone Programming
(ASCE, 2/1/2021)This paper aims at analyzing the active and passive lateral earth pressures exerted on retaining walls due to the anisotropic medium of dry and noncohesive backfill subjected to the modified pseudodynamic earthquake loading. ... -
Stability Investigation of a Deep Shaft Using Different Methods
(ASCE, 2/1/2021)The New Zigana Tunnel is, at 14.5 km long, the longest highway tunnel project in Turkey. In this project, it is planned to construct two service shafts to provide access to outside the tunnel and temporary ventilation. ... -
Influence of the Spatial Variability of Soil Shear Strength on Deep Excavation: A Case Study of a Bangkok Underground MRT Station
