Effects of reservoir water level fluctuations and rainfall on a landslide by two-way ANOVA and K-means clustering

期刊: BULLETIN OF ENGINEERING GEOLOGY AND THE ENVIRONMENT, 2021; 80 (7)

The deformation and failure of reservoir landslides are typically affected by reservoir water level fluctuations, rainfall, and their jointed influenc......

Noise reduction method of microseismic signal of water inrush in tunnel based on variational mode method

期刊: BULLETIN OF ENGINEERING GEOLOGY AND THE ENVIRONMENT, 2021; 80 (8)

The extraction of effective signals of microseismic event caused by water inrush in tunnels is an important prerequisite for accurate location of even......

Effect of oxygen on damage mechanism and mechanical properties of sandstone at high temperature

期刊: BULLETIN OF ENGINEERING GEOLOGY AND THE ENVIRONMENT, 2021; 80 (8)

The effect of oxygen on the microstructure and mechanical properties of thermally treated rocks is a matter of rock engineering. For comparative analy......

Physical test of fracture development in the overburden strata above the goaf and diffusion process of permeable grout slurry

期刊: BULLETIN OF ENGINEERING GEOLOGY AND THE ENVIRONMENT, 2021; 80 (6)

The massive mechanized and irrational coal mining has generated many goafs (i.e., mined-out areas) in China. To manage these goafs effectively, grouti......

Back analysis of surrounding rock parameters of tunnel considering displacement loss and space effect

期刊: BULLETIN OF ENGINEERING GEOLOGY AND THE ENVIRONMENT, 2021; 80 (7)

Displacement back analysis is often performed to estimate rock parameters in tunnel construction. However, most researchers use the final values of mo......

Theoretical and numerical investigations on mining-induced fault activation and groundwater outburst of coal seam floor

期刊: BULLETIN OF ENGINEERING GEOLOGY AND THE ENVIRONMENT, 2021; 80 (7)

Mining activities carried out above an aquifer, especially in the hanging wall of normal faults, generally involve the risk of water inrush. For a bet......

Shear creep experiments and modeling of granite under dry-wet cycling

期刊: BULLETIN OF ENGINEERING GEOLOGY AND THE ENVIRONMENT, 2021; 80 (7)

Repeated dry-wet cycling can substantially alter rock mechanical properties, which poses a serious risk to the safety and stability of geotechnical en......

Study of the repeated collapsibility of undisturbed loess in Guyuan, China

期刊: BULLETIN OF ENGINEERING GEOLOGY AND THE ENVIRONMENT, 2021; 80 (8)

At present, the international evaluation method of loess collapsibility only evaluates loess once collapses, but some scholars have found that loess i......

Prediction of an early failure point using infrared radiation characteristics and energy evolution for sandstone with different water contents

期刊: BULLETIN OF ENGINEERING GEOLOGY AND THE ENVIRONMENT, 2021; 80 (9)

Water is one of the most effective agents that weaken the physio-mechanical properties of rock, trigger significant construction delays, endanger the ......

Detecting freeze-thaw damage degradation of sandstone with initial damage using NMR technology

期刊: BULLETIN OF ENGINEERING GEOLOGY AND THE ENVIRONMENT, 2021; 80 (6)

The nuclear magnetic resonance (NMR) technique was used to study freeze-thaw damage degradation of sandstone with initial damage. The initial damage w......

Investigation of the strength recovery characteristics of a red-bed landslide soil by SHS and ultrasonic experiments

期刊: BULLETIN OF ENGINEERING GEOLOGY AND THE ENVIRONMENT, 2021; 80 (7)

The strength recovery (healing) of the shear zone soil of a landslide during the dormant phase after the sliding affects the reactivation of the lands......

In situ grouting tests for differential settlement treatment of a cut-and-cover metro tunnel in soft soils

期刊: BULLETIN OF ENGINEERING GEOLOGY AND THE ENVIRONMENT, 2021; 80 (8)

This paper presents three comparative in situ grouting tests for long-term settlement treatment of a cut-and-cover tunnel of Nanjing Metro Line 10. Th......
