The purpose of this study is to identify the leading causes slope instability along a local highway in Anhui, People’s Republic China. As part east expansion project, mountain range will be excavated create two-way, nearly 30 m wide highway. site’s topography consists hill with palm-shaped faces carved from limestone running its sides. geological characteristics and stability research area high...

Estimation of the possible instability that may be encountered in the excavation slope(s) during the planning and application steps of the rock excavation processes is an important issue in geoengineering. In this paper, a modelling method is presented for assessing the probability of wedge failure involving new permanent or temporary slope(s) along the planned excavation dir...

We employ a model of leverage-induced explosive behavior in financial markets to develop a measure of financial market instability. Specifically, we derive a quantitative condition for how large levered investors can become relative to the whole market before the demand curve for securities suddenly becomes upward-sloping and small price declines cascade as levered investors are forced to liqui...

Following earthquake events multiple soil slope failures are observed throughout the structurally fragile soil and rock in North Island, New Zealand. Many of these slopes are located in close proximity to various assets including residential buildings and roads, resulting in damage to the structures. Limited mitigation solutions are available to stabilise both the global integrity and surficial...

Softening is often considered to be the main cause of first-time slides in OC clay, but so far the mechanics of softening has not been satisfactorily explained. Bearing on laboratory data and field observations about landslides in tectonized highly plastic clay shales of Italian Apennines, the paper describes a process of soil weakening that could explain some failures of natural slopes.

This work presents a determination method of rainfall types based on rainfall-induced slope instability to provide an effective approach for early warning different patterns failures/landslides. Firstly, 5808 scenarios are simulated with 11 kinds soil properties under 528 designed intensity-duration (I?D) conditions get the threshold curves failure and properties. Then through analysis when occ...

Optimal delivery of chemotherapy intensity is dependent on host- and tumor-specific characteristics. In this article, the chemotherapy late intensity schedule is revised to account for tumor growth instability, where a small tumor cell fraction emerges that exhibits a higher proliferation rate than the parent strain. Modeling this instability as simplified two-population dynamics, we find that:...
