Abstract

When designing a parking lot of limited size with a large elevation difference, a decision to construct an earth embankment with a retaining wall was made. Based on the analysis of the results of engineering geological surveys and construction conditions, four options of constructing a retaining wall were considered. The stress-strain states of the protective structures and embankments were studied in details with the help of finite element modeling in order to select the optimal technical solutions for retaining walls. Based on the analysis of the distribution of stresses and strains in the structures, the advantages and disadvantages of each option are determined. The optimal combined version of constructing a thin retaining wall with unloading screens and hardening of the embankment by means of anchor-injectors is substantiated.

Highlights

In modern conditions, the problem of free territories appropriate for building even in regional towns remains very relevant
Since the load on the retaining wall is formed due to the formation of a creeping prism (Fig. 5), the parameters of which are determined by the height of the embankment, the characteristics of the soil and the weight of the vehicles, it is possible to solve this problem by using the bearing ability of fillings
As they being laid in concrete, holes are made for the passage of perforated pipes

Summary

Introduction

The problem of free territories appropriate for building even in regional towns remains very relevant. To organize a parking lot near facility under construction in town Shakhty, a site was required, but the specifics of the relief and the dense area development made it difficult. It was a territory free of building with a width of 23.5 m limited by the embankment of the road and the security zone of the main gas pipeline. Obtaining the required parking area, taking into account the security zone of the gas pipeline, is possible only with the construction of a retaining wall on the east side of the construction site
