Abstract

A practical way to utilize the underground space of buildings is deepening the basement. Where peat is found under the building basement, floor construction proves to be a challenging engineering problem. The article describes several basement floor construction methods for building reconstruction on peaty soils in the city of Arkhangelsk. Peaty soils require bored, driven or jacked piles up to 8 m long. Due to continuous peat consolidation, "floating" floors resting on the ground cannot be used. Numerical simulation of piles in PLAXIS 3D software provides load-settlement curves closely correlating with the results of static load tests.

Summary

Introduction

При наличии в основании торфа устройство полов является сложной технической задачей. В статье представлены способы устройства полов для подземных этажей при реконструкции зданий на заторфованной территории г. Результаты численного моделирования свай по программе PLAXIS 3D позволяют получить графики «нагрузка-осадка», близкие к данным натурных испытаний статической нагрузкой. Where peat is found under the building basement, floor construction proves to be a challenging engineering problem.
