Effect of Overburden Height on Hydraulic Fracturing of Concrete-Lined Pressure Tunnels Excavated in Intact Rock: A Numerical Study

Fluids, 2019
This study investigated the impact of overburden height on the hydraulic fracturing of a concrete-lined pressure tunnel, excavated in intact rock, under steady-state and transient-state conditions.

Hydraulic and mechanical properties of glacial sediments beneath Unteraargletscher, Switzerland: implications for glacier basal motion [PDF]

, 2001
The force on a ‘ploughmeter’ and subglacial water pressure have been measured in the same borehole at Unteraargletscher, Switzerland, in order to investigate ice–sediment coupling and the motion at the base of a soft-bedded glacier.

The influence of overburden pressure on liquefaction potential

TURKISH JOURNAL OF ENGINEERING AND ENVIRONMENTAL SCIENCES, 2014
One of the important design considerations for structures situated on sand deposits is the potential for instability caused by the development of excess pore water pressure as a result of earthquake loading. A build-up of excess pore water pressure may lead to initial liquefaction.

Numerical modelling of mud volcanoes and their flows using constraints from the Gulf of Cadiz [PDF]

, 2003
It is estimated that the total number of submarine mud volcanoes is between 1000 and 100 000. Because many are associated with greenhouse gases, such as methane, it is argued that the global flux of these gases to the atmosphere from the world’s ...

Study on overburden movement law and ground pressure behavior in fully mechanized top coal caving face under the disturbance of upper coal seam

Meikuang Anquan, 2023
In recent years, most of the coal mines in Zhungeer Coalfield have entered the mining of the second main coal seams, such as 6#, 10# and 11#, with an average thickness of more than 10 m, so most of the coal mines use fully mechanized caving mining ...

Field investigation of deformation characteristics and stress mobilisation of a soil slope [PDF]

, 2015
Stress mobilisation and deformation of a slope are important for engineers to carry out reliable design of retaining systems. However, most case histories reported mainly on the response of pore-water pressure (PWP), whereas knowledge about the stress ...

Finite Element Modeling of the Soil-Nailing Process in Nailed-Soil Slopes

Applied Sciences, 2023
The finite element technique has been accepted as a tool for modeling geotechnical complex processes. In this study, finite element (FE) modeling of various stages of the soil-nailing process, i.e., construction stages and overburden pressure stages, is ...
