GPR Condition Survey of the Fill Slope of the River Dam

2020 IEEE Ukrainian Microwave Week (UkrMW), 2020
This paper presents the results of a survey of the slope of an earthen dam using GPR. The purpose of the survey was to determine local dam zones with high humidity. The survey was carried out using SFCW GPR along the entire slope of the dam.

Relationship between earthquake-induced excess pore water pressure and strong ground motion observed in a monitored fill slope

Engineering Geology, 2020
The generation of excess pore water pressures during ground shaking can be an important earthquake-induced landslide trigger. We measured pore water pressures and seismic ground motion in filled slopes and examined their relationships obtained from 29 ...

Slope Stability Analysis for Filled Slopes Using Finite Element Limit Analysis Method

Soil Behavior and Geomechanics, 2014
This paper uses the finite element upper and lower bound limit analysis to assess the stability of slopes mostly found in embankment cases where frictional materials are filled on purely cohesive undrained clay. For comparison purposes, the commonly used stability assessment method, limit equilibrium method (LEM) is also employed. The final results for

Model test study on the hydrological mechanisms and early warning thresholds for loess fill slope failure induced by rainfall

Engineering Geology, 2019
Under rainfall conditions, the characteristics of hydraulic changes related to the failure evolution of fill slopes are critical to the early warning of slope failure.

Mean Parametric Monte Carlo Study of Fill Slopes

International Journal of Geomechanics, 2017
AbstractSlope stability analysis has traditionally been performed using a deterministic approach. However, it has strongly been debated that the use of only the factor of safety in slope stability analysis does not explicitly account for all the uncertainties in soil parameters.

A case study integrating field measurements and numerical analysis of high-fill slope stabilized with cast-in-place piles in Yunnan, China

Engineering Geology, 2019
A high-fill slope located in Zhenxiong County, Yunnan Province, China, was designed for building placement on its top platform. A reinforcement system consisting of a geogrid, front stability piles (FSPs), retaining sheets, prestressed anchors, and rear ...

Time Series Analysis and Temporal Stability of Shallow Soil Moisture in a High-Fill Slope of the Loess Plateau, China

Water
Precipitation-induced soil moisture dynamics are a key factor that plays a critical role in triggering slope failures and geological hazards. This study investigates the response of soil moisture in a high-fill slope to rainfall and explores the ...

Fill‐Slope Failure and Repair

Journal of Performance of Constructed Facilities, 1992
The paper describes the failure and repair of a fill slope at Caminito Muirfield Street, La Jolla, California. There were several factors that contributed to the movement of the fill slope and the damage to the condominiums. One factor is that the condominiums were built very close to the top of slope, and when there was deformation due to slope creep,
