Abstract. This article is part of the dissertation «Improving the Calculation Methods and Design Forms of Soil-Backfilled Artificial Structures Made of Steel Fiber Reinforced Concrete».

The author’s previous research includes an analysis of each of the following standards: Russia — Code of Practice SP 35.13330.2011 «Bridges and Pipes»; America — AASHTO LRFD Bridge Design Specifications; New Zealand and Australia — Standard AS/NZS 3725, related to the collection of permanent and temporary earth pressure loads on buried structures, such as culverts in embankments, specifically the comparison of vertical and lateral earth pressures on the walls and base (trough) of culverts. It was concluded that determining the stress distribution in the soil mass and, consequently, the pressure on the culvert body is a complex, multi-step task due to the lack of computational models for the interaction of buried structures and the surrounding backfill soil mass, as well as changes in soil characteristics such as the angle of internal friction (φ), the coefficient of adhesion (C), and the bulk density of soil (ρ) over the life of the structure. Determining earth pressure is a complex, multifaceted task and is determined by a number of factors, such as the rigidity of the culvert, installation conditions, the adopted foundation, and the characteristics of the backfill soil after compaction. This article examines the main and most well-known international theories for determining soil pressure on buried structures, models for stress distribution in soil masses, and the fundamental principles of international methods for the direct and indirect design of rigid concrete pipes.

For each standard, several load cases are considered to determine the required area of working reinforcement, using pipe parameters such as diameter and wall thickness as variables.
