CALCULATING SHORING SYSTEMS FOR A DEEP EXCAVATION BY SOIL-STRUCTURE INTERACTION ANALYSIS

Abstract

Need of using underground space to build contructions in big cities like HoChi Minh City is becoming more and more popular and urgent, Those constructions have structure parts which is placed in subsoil. This demands calculating or controlling shoring systems more complex and high requirement, especially in conditions of narrow construction site and soft soil. At present, the popular method to calculate shoring systems is the approximative method based on Coulomb's earth pressure theory. The soil- Structure Interaction Analysis by finite element method with support of PLAXIS 7.2 allows us to calculate or control stability and deformation of soilbase and shoring systems in different building periods.
