МЕТОД РАСЧЕТА ДАВЛЕНИЯ ГРУНТА, ДЕЙСТВУЮЩЕГО НА ПОДПОРНУЮ СТЕНКУ, С УЧЕТОМ ВЛИЯНИЯ СОСЕДНЕГО ОДНОСВАЙНОГО СОСТАВНОГО ФУНДАМЕНТА A method for calculating the earth pressure acting on retaining wall considering the effect of an adjacent single pile composite foundation

Аннотация


Приводится методика расчета горизонтального давления на подпорную стенку, вблизи которой расположен односвайный составной (плита, амортизирующий слой между плитой и верхом сваи и собственно свая) фундамент, с учетом взаимодействия сваи с грунтом внутри композитного фундамента. Проведено сравнение предлагаемого и существующих методов расчета, которое показывает, что существующие методы, в которых игнорируется указанное взаимодействие, могут в значительной степени как переоценивать, так и недооценивать давление грунта. Проведен анализ величины давления на подпорную стенку в зависимости от расстояния составного фундамента от стенки и диаметра свай. Приведены данные модельных экспериментов в лотке, подтверждающие обоснованность предлагаемого метода.
