Abstract

Terrain drainage in the landslide area on the Danube slope in Novi Sad

Highlights

  • Landslides on the right bank of the Danube in Serbia are large and deep and have very specific features

  • This paper demonstrates that the main causes behind the creation of landslides are the following: sediments that are mildly tilted towards the Danube; the frequency of low-resistance sediments along which the sliding takes place; the influence of groundwater flowing from the slope part of the terrain into the landslide; and the Danube itself, due to its deep river bed that erodes the right river bank

  • We would like to point out the investigations that were carried out during the excavation and construction of the two deep drainage wells and the drainage tunnel

Summary

Introduction

Landslides on the right bank of the Danube in Serbia are large and deep and have very specific features. This paper demonstrates that the main causes behind the creation of landslides are the following: sediments that are mildly tilted towards the Danube; the frequency of low-resistance sediments along which the sliding takes place; the influence of groundwater flowing from the slope part of the terrain into the landslide; and the Danube itself, due to its deep river bed that erodes the right river bank. On the right bank of the Danube, the pillars of the bridge were founded on relatively deep piles (Fig. 2) except for the final pillar, number 22, which was founded on a raft without piles. The movements of the pillars are being geodetically measured Based on these measurements, it Terrain drainage in the landslide area on the Danube slope in Novi Sad is possible to analyse the dynamics by which the landslide and the bridge are moving. The results of years of measurement were crucial for forming the decision that the unstable slope in the area around the bridge must be stabilised
