Abstract

Abstract In the paper the numerical modelling of ensuring slope stability and their analysing with using of different numerical methods are presented. We have designed the cutting walls with earth nails and anchors securing for modelling of slope stability ensuring. The calculate and the mechanism of failure process of the reinforced slopes were studied using the different methods for slope stability. The nailing significantly increased the stability level for using Spencer method. The anchors increased the stability level for using Spencer method. Increasing the nail or anchors length improved the stability of the reinforced slopes. The reinforced slope exhibited a significant the stability level.

Highlights

The problem of slope stability is very topical when evaluating the stability of existing slopes, and in the implementation of new slopes or excavations
If we compare variants without ensuring of slope stability (Variant A to Variant D), Variant D gives the highest safety factors for all methods used for calculation of the problem
The safety factors calculated for the Variant B are unsatisfactory and we proposed Variant C

Summary

Introduction

The problem of slope stability is very topical when evaluating the stability of existing slopes, and in the implementation of new slopes or excavations. High embankments or notches must be realized especially in civil engineering constructions. The slope face can deform, and this may lead to landsliding especially in during excavation work of natural slopes. Landslide is caused by a combination of climatic, geological, and geomorphological factors in response to triggering mechanisms (most often are heavy rain, seismicity, or human activity). Landslides cause huge socio-economic losses due to environmental degradation. They directly affect construction, which requires the use best practices for long-term mitigation and reduction of landslide risk. In this context, knowledge of geological and geomorphological conditions and numerical modelling provide effective protection against landslides)
