Введение. В мировой практике ячеистые конструкции применяются в качестве как временных, так и постоянных сооружений. Они изготавливаются из взаимосвязанных шпунтовых свай, образующих смежные ячейки, и обычно заполняются грунтом обратной засыпки. При использовании ячеистых конструкций в качестве перемычки массивные ячейки позволяют проводить работы насухо и при необходимости производить выемку грунта основания на небольшую глубину. Так как в шпунте ячеистых конструкций из-за их формы практически не возникает изгибающих моментов, а работают они в основном на растяжение, в них применяются плоские шпунтовые сваи.

Материалы и методы

Материалы и методы. Выполнены проверки устойчивости ячеистой конструкции в соответствии с действующими нормативными документами. Для анализа и сравнения методик расчета устойчивости выбрано несколько диаметров и несколько глубин погружения шпунта. Помимо устойчивости для всех расчетных сечений определен коэффициент запаса по прочности замков. Полученные аналитическими методами результаты сравнивались с результатами, полученными в расчетном комплексе Midas FEA NX в двухмерной и трехмерной постановке.

Результаты

Результаты. Получены графики зависимости коэффициентов устойчивости от заглубления и диаметра ячеистой конструкции. Проведено сравнение результатов, полученных в расчетном комплексе Midas FEA NX в двухмерной и трехмерной постановке, с аналитическими методами расчетов устойчивости.

Выводы

Выводы. Численное моделирование в двухмерной постановке задачи дает схожие результаты с аналитическим решением и значительно меньший запас устойчивости в сравнении с трехмерной задачей.

Introduction

Introduction. Cellular structures are internationally used as temporary and permanent structures. They are made of interconnected sheet piles forming adjacent cells, and they are usually filled with backfilling soil. When cellular structures are used as cofferdams, massive cells (1) make the use of cement and mortar unnecessary and (2) allow for the foundation soil to be excavated to a shallow depth. Since there are practically no bending moments in sheet piles of cellular structures due to their shape and sheet piles are mainly in tension, flat sheet piles are used to make these structures.

Materials and methods

Materials and methods. In this study, stability of a cellular structure was analyzed in compliance with effective regulatory documents. Several values of (1) the diameter of sheet piles and (2) the sheet pile driving depth were selected to study and compare methods of stability analysis. In addition to stability, the safety factor of interlocks was found for all design sections. Analytically obtained results were compared with those computed in two- and three-dimensional settings using Midas FEA NX software package.

Results

Results. Graphs were made to demonstrate the dependence between stability factors, the depth and the diameter of a cellular structure. The results computed in two- and three-dimensional settings using Midas FEA NX software package were compared with those obtained using analytical methods of stability analysis.

Conclusions

Conclusions. Results of numerical modeling made in the two-dimensional setting are similar to the analytical solution. They show a substantially smaller stability factor compared to the three-dimensional problem.
