Influence of a weak layer on the tunnel face stability – Reliability and sensitivity analysis

, 2020
In this study, reliability and sensitivity analyses were employed to investigate the effects of a weak interlayer on tunnel face stability. Due to the irregular geology process and the movement of tunnelling machine, the situations of weak soils ...

Influence of rheologically weak layers on fault architecture: insights from analogue models in the context of the Northern Alpine Foreland Basin

Swiss Journal of Geosciences, 2022
We present a series of analogue models inspired by the geology of the Zürcher Weinland region in the Northern Alpine Foreland Basin of Switzerland to explore the influence of rheological weak, i.e.

Characteristics of strength reduction in the weak layer and large-slip displacement of the cut slope on the Fushun west open-pit mining area

Zhongguo dizhi zaihai yu fangzhi xuebao, 2023
The strength attenuation characteristics of the weak interlayers are one of the key factors leading to instability of the bedding rock slopes. In this study, the Nanbang slope of Fushun west open-pit mine was selected as the research object.
