To investigate influence of underwater environment on the effect of underwater drilling and blasting, the action mechanism of underwater drilling and blasting was analyzed by taking the underwater blasting engineering of No.3 pier foundation of …

The design of shallow foundations for wind turbines is typically governed by serviceability and fatigue limit states. To estimate the deformations of shallow foundations under working loads, existing design standards generally employ analytical …

Solitary boulders emerge in the thick-bed red sandstone in the Chishui red bed area due to weathering, which can potentially induce engineering disasters. This paper measures the porosity, pore size, pore throat distribution, T2 spectrum …

This paper focuses on a pullout failure of anchor rods used to stabilize rock slope at the sides of a road cut in a mountainous terrain. The objectives of this work are to analyze a case study of a pullout type of failure of anchor rods at highly …

The deformation, strength, and failure characteristics of layered composite sandstones (LCSs) are critical issues in a stability evaluation in underground engineering. These issues were examined in this study using true triaxial experiments, with …

A buried utility tunnel can effectively protect internal pipes by preventing or mitigating corrosion, external damage, and facilitating maintenance. During an earthquake, the energy from seismic waves is transmitted through the soil to the utility …

To investigate the effect of in-pit vehicle load on the stability of the pit against overturning, a long tunnel foundation pit project in Suzhou is used as a case. In-pit vehicle load effects are modelled using the improved equivalent soil …

Residual stresses refer to those stresses from sources other than contemporary tectonic forces that are locked within the rock formation. These stresses could develop and be stored within the rock during the cooling process of rock formation …

Understanding the time-dependent behavior of the rock mass is crucial to improve the reliability of underground structure design, particularly for projects with longer lifespans, such as nuclear waste repositories and hydrocarbon storage tanks.

Monopiles serve as the foundational support for offshore wind turbines and are constructed as large, hollow, and rigid steel pipes. Given their offshore installation, these foundations experience cyclic lateral forces from wind and waves. This …

This research paper assesses the geomechanical performance of a composite material comprising gold ore tailings and polymeric fibers in geotechnical structures. It involves a suite of geotechnical characterization assessments, compaction trials …

The control of surface heaving has been of interest in major applications of compaction grouting such as ground improvement and settlement compensation works. Some studies generalize compaction grouting as heave-inducing and thus the corresponding …

For many civil and mining engineering structures, rock is the primary construction medium. At engineering scales, the material of interest is the “rockmass,” which contains sections of intact rock separated by a network of pre-existing joints …

Transversely Isotropic (TI) rocks exhibit anisotropic strength characteristics due to uniform structural features such as foliation, lamination, schistosity, cleavage planes, layering, bedding planes, and stratified layers. In the field of rock …

Internal instability establishes when fine particles of bimodal soil migrate with seepage flow into voids created by coarse fabric, altering the original gradation. The tendency for soils to undergo internal instability centres on their compaction …

The effect of electrokinetic sodium silicate injection into sand formation containing fine grains was studied in this research. A soil was grouted by Na-silicate in a 160 mm length electrokinetic cell with a 1 V/cm potential gradient for 1 week.

The occurrence of a series of earthquakes of different magnitudes or multiple mainshocks has been reported recently. This leads to the liquefaction of sand due to excess pore pressure generation under undrained loading conditions, which alters the …

Experimental and analytical researches have shown that the use of the bottom air-deck blasting improves fragmentation and reduces toe problems. In this research modelling of bottom air-deck blasting in a single hole, using numerical methods was …

Soil–rock mixture, a non-homogeneous medium with discrete characteristics, is commonly used in high-fill projects. This study analyzes the impact of rock morphology and distribution on the ultimate bearing capacity and sliding failure surface …
