Seismic loading impacts on excess pore‐water pressure maintain landslide triggered flowslides

Earth Surface Processes and Landforms, 2008
AbstractDuring the 2003 Sanriku‐Minami earthquake, Japan, a flowslide was triggered on a slope of about 13.5º. The displaced landslide mass developed into a flowslide and deposited on a horizontal rice paddy after traveling approximately 130 m. To study the trigger and movement mechanisms of this landslide, field investigation and laboratory ring‐shear

Agitation and its control on excess pore water pressure and debris‐flow behaviour

Earth Surface Processes and Landforms, 2023
AbstractExcess water pressure strongly affects the rheology and flow behaviour of debris flows, and the mechanisms for development and persistence of the pressure can be diverse. Using nine experimental slurries prepared with the sediments collected from the deposit of a large‐magnitude debris flow by modifying maximum grain size and solid ...

Simulation of excess pore water pressure during deep soil mixing columns installing

Journal of Shanghai Jiaotong University (Science), 2012
Most of current studies of deep soil mixing (DSM) methods are focused on the soil strength improvement and soil treatment effectiveness. But the DSM installation leads to excess pore water pressure and soil disturbance, which will bring great harm to adjacent structures, such as shell tunnels and historic buildings.

Estimating Consolidation Coefficient and Final Settlement: Triangular Excess Pore-Water Pressure

Journal of Geotechnical and Geoenvironmental Engineering, 2005
The exact analytical solutions for the one-dimensional transient consolidation settlement of clay under triangular loadings of pore-water pressure are presented. Using these solutions, two new methods, a “diagnostic curve” method and a “peak derivative” method are developed for a simultaneous estimation of the coefficient of consolidation and final ...

Development of Excess Pore Water Pressure around Piles Excited by Pure Vertical Vibration

International Journal of Civil Engineering, 2016
In this study, an assessment to excess pore water pressure generated around a single pile and pile group excited by two opposite rotary machines embedded in saturated sandy soil was considered experimentally. A small-scale physical model was manufactured to accomplish the experimental work in the laboratory.

Approximate Simple Invertible Equations for Consolidation Curves Under Triangular Excess Pore-water Pressures

Geotechnical and Geological Engineering, 2007
Approximate but accurate, simple invertible equations for the consolidation curves under triangular excess pore-water pressures are developed. These approximations can be used to calculate the degree of consolidation corresponding to a specified time factor (explicit) or the time factor corresponding to a specified degree of consolidation (implicit ...

Study on the Changing Rule of Excess Pore Water Pressure during Dynamic Compaction

Applied Mechanics and Materials, 2011
The changing rule of excess pore water pressure during dynamic compaction is important for construction. The following conclusions could be drawn by observing and analyzing the excess pore water pressure in test area. Under ramming strike energy of 2000kN•m, the best hit number during the 1~2 times is 8~9, the best hit number during the third time is 6~

Consolidated Characteristics and Excess Pore Water Pressures of Mississippi Fan Sediments

1985
Examination of the geotechnical properties of the Quaternary sediments from the middle and lower portions of the Mississippi Fan shows that the sediments are normally consolidated to overconsolidated to a depth of 40 to 50 below the seafloor. Beyond that depth, the sediments become highly underconsolidated and exhibit high excess pore water pressures ...
