This paper presents shakedown analysis of a half-space obeying Von-Mises criterion under Hertz loads in plane strain model. Based on the static shakedown theorem, a rigorous shakedown solution is established by searching...

Abstract Thick-hard roof fracturing presents a significant challenge for disaster prevention in longwall mining. This study investigates the 15,311 south working face and develops a mechanical model to analyze energy rel...

Based on a large-scale excavation adjacent to metro line, the design and construction schemes and monitoring data of metro structures during construction are analyzed. Some conclusions are drawn as follows: the movement ...

A comprehensive structural, petrological, and geophysical study of the 385 ± 2 Ma Devonian El Hornito Pluton (EHP) in the Sierra Grande de San Luis, Argentina, is presented. We establish that the EHP results from the in...

The rock-cut heritage of the Kayseri Valleys represents a distinctive vernacular tradition shaped by technological skill, social practices, and environmental adaptation. These systems, evolving from carved spaces to maso...

The case study of closely spaced twin tunnels excavated vertically beneath the adjacent Chaoyangmen station in Beijing, China is introduced. The existing subway station is part of the Beijing subway Line 2. The new recta...

The discontinuities distributed in underground structures are the important factors that affect the mechanical characteristics of rock mass, and to study the mechanical behavior of rock discontinuities under cyclic loadi...

BackgroundIn practical engineering, the waterproof coal pillar usually suffers from different degrees of dynamic load from the overlying strata, and its internal water distribution is non-uniform. Although the traditiona...

A hybrid technique, FEM-IBIEM is developed for studying the scattering of seismic waves by a 3-D complex local site. The indirect boundary integral equation method (IBIEM) adopts the dynamic Green's functions of concentr...

This study investigates the fragmentation expansion and water storage characteristics of collapsed rock in overlying strata during its formation. Pre-static loaded fractured samples of four typical roof rock types-coarse...

Qwing to that the common cement paste used in the complex soil strata with wide steep seams and loose space cannot fill firmly and run along the gaps, a new type of SJP cement paste is developed, which has great initial ...

When using the blasting caving method to treat goaf, the collapsing ore and rock can cause shock disturbances to the roof of the lower stope, which may lead to stability risks. This study takes the goaf treatment project...

Based on the Biot's theory of the two-phased poroelasticity medium, a coupled model for a saturated layered ground containing an open trench and track is developed, and the effect of the open trench on reducing the vibra...

ObjectiveThe conventional inversion of surface direct-current (DC) resistivity data faces challenges such as limited exploration accuracy and depth. This study aims to enhance the accuracy and reliability of exploration ...

Lawns and wooded areas dominate urban green spaces (UGSs) and are known to store substantial amounts of carbon in soils, yet the role of lawn trees in litter decomposition dynamics remains poorly understood. This study a...

ObjectiveRescue drilling rigs undergo intense vibration at borehole mouths when operating in a confined underground space of coal mines. To address this issue, this study designed a compact multi-directional, passive dyn...

Based on the framework of thermodynamics and critical state soil mechanics, a new α-β yield surface is formulated in the triaxial space. Based on the non-associated flow rule and bounding surface framework, the propose...

Based on the concept of true stress and the strain equivalence hypothesis, a three-dimension elastic-plastic damage constitutive model for rock is established. Combining the nonlinear unified strength model as the yield ...

The new computer program SHELXT employs a novel dual-space algorithm to solve the phase problem for single-crystal reflection data expanded to the space group P1. Missing data are taken into account and the resolution ex...

The Shuttle Radar Topography Mission produced the most complete, highest‐resolution digital elevation model of the Earth. The project was a joint endeavor of NASA, the National Geospatial‐Intelligence Agency, and the...
