Automated assessment of slope stability: Application of machine learning to ERT monitoring data andintegration with geomechanical models

Landslides pose a risks to the communities settled in their vicinity. They pose a threat to human lives and significant economical damage to the affected communities. As the scientific community agrees that the climate change will further increase the risks associated with landslides, it is important to develop a reliable, cost effective and...

A New Approach for Slope Stability Analysis: Combining the limit equilibrium method and finite element method

A new approach is proposed which uses concepts of both the limit equilibrium method (LEM) and finite element method (FEM) to analyse slope stability. The main limitation of the LEM is that it can give an incorrect display of the initial stresses. The FEM is able to overcome this limitation, however, it uses the shear strength reduction method ...

A Metamodelling Approach to Reliability Updating with Dike Construction Survival

The construction of a dike improvement often causes a decrease in reliability during construction. Raising a dike may give rise to excess pore water pressures in the subsoil, resulting in a temporal strength decrease. Observing the survival of such a loading condition might provide information on the strength of a dike. Therefore, this research...

Dike stabilisation under uplift conditions using stabilisation columns: A study on the technical potential of stabilisation columns for improving inner slope stability under uplift conditions

The low lying areas in the Netherlands often consist of soft and low permeable soils like clay and peat on top of a sand layer. Due to high water pressures at the interface between the permeable sand layer and the low permeable top layers, the effective stresses decrease, which can cause lifting of the low permeable top layers. As a consequence...

Interaction between the failure mechanisms backward erosion piping and slope instability: Identification and quantification of interactions between failure mechanisms of a levee

With the shift of the safety standards for levees from exceedance probability (standard 1996) to flooding probability (new standard), the part of the levee failure process after the initial occurrence of a failure mechanism becomes more important for the calculation of the strength and thus, reliability of the levee cross-section. Interactions...

Pile installation in submerged sandy slopes: Assessing liquefaction-induced instability

Loose, sandy slopes situated or deposited under water may be susceptible to liquefaction-induced failure. In contrast to 'regular' localised slope failures, flow slides are diffuse, large-scale and potentially disastrous. Earthquake-induced ground vibrations currently dominate the liquefaction engineering scene. In reality, however, many...

Updated rock mechanical design criteria for the Liikavaara Östra open pit

The assessment of rock mechanical data is a fundamental step in the process of evaluating the profitability of an open pit mine. The steepness of bench, interramp and resulting overall slope angles have a direct effect on the stripping ratio, therefore on the profitability of the mining operation. With the recently challenging metal prices in...

Slope stability analysis based on random finite element method and probabilistic approach

In this work, an investigation into generic slope stability is carried out. The investigation takes into account slope parameters of height (H) and slope gradient (?) as well as material parameters of shear strength (vc) and spatial correlation length (?). A Monte Carlo analysis of many slopes with randomly generated shear strength parameters is...

Flow slide failure of excavated subaqueous slopes

Unexpected failure of subaqueous excavated slopes in the form of flow slides is considered in this graduate study. Excavated slopes are not the same as slopes constructed by means of hydraulic fill. Several recent flow slide failures in sand borrow pits, together with qualms in engineering practice about not knowing exactly what fundamental...
