Development law and growth model of dynamic pore water pressure of tailings under different consolidation conditions [PDF]

PLoS ONE, 2022
Tailings dams are in danger of liquefaction during earthquakes. The liquefaction process can be indirectly reflected by the evolution rule of the dynamic pore water pressure.

Field Test of Excess Pore Water Pressure at Pile–Soil Interface Caused by PHC Pipe Pile Penetration Based on Silicon Piezoresistive Sensor [PDF]

Sensors, 2020
Prestressed high-strength concrete (PHC) pipe pile with the static press-in method has been widely used in recent years. The generation and dissipation of excess pore water pressure at the pile–soil interface during pile jacking have an important ...

A new method for determining the pore water pressure around twin shallow circular tunnels [PDF]

Scientific Reports
To obtain the distribution rules of pore water pressure for twin shallow circular tunnels, the shallow circular tunnels were regarded as fully saturated, homogeneous, isotropic structures in a semi-infinite space. Coordinate transformations were utilized

Dynamic pore water pressure in saturated soil due to turbine engine’s vibration [PDF]

E3S Web of Conferences, 2023
The turbine engine that is operating will generate vibrations that are transmitted by the foundation into the soil layer. This causes the pore water pressure in the soil to increase, which causes the shear strength of the soil to decrease and can reduce ...
