Abstract

The following are the research results made both at lengthwise and width directions with and without accounting sequence of a section erection. Calculations were performed in the maths laboratory of «B.E. Vedeneev VNIIG» with software assistance. The main aim of the study is to search for the optimal stress-strain behavior of the dam in terms of forming minimal tension in concrete.

Highlights

While designing such critical structures as concrete dams, it is very important to analyze their stress-strain behavior [1,2,3,4,5,6]
In operative design and construction specifications [7] when choosing structural design of a concrete dam including ones on soils, it is recommended to take into account the sequence of its erection and loads
The majority of works, concerning this issue were published at the time when calculation methods as well as abilities of PC remarkably limited possibilities of problem solving even in the context of plane elasticity

Summary

Introduction

While designing such critical structures as concrete dams, it is very important to analyze their stress-strain behavior [1,2,3,4,5,6]. Nowadays a stress-strain behavior of mass concrete dams on soils at various stages of its erection and loads is quite understudied. As for account of piers, plane strain problem of body interacting with foundation was solved. Hydrostatical pressure and backpressure along the foot of a dam were exerted to the section erected by that time.
