ПРОГНОЗ ОСАДОК ПРИ ЩИТОВОЙ ПРОХОДКЕ ПАРАЛЛЕЛЬНЫХ ТОННЕЛЕЙ STUDY OF THE SETTLEMENT PREDICTION OF A DOUBLE LINE SHIELD TUNNEL CONSTRUCTED SUCCESSIVELY IN UPPER SOFT AND LOWER HARD STRATAS

Аннотация


Для прогноза осадок дневной поверхности при последовательной щитовой проходке перегонных тоннелей метрополитена в Циндао предлагается применять скорректированное уравнение Пека. Проверка методами численного моделирования и полевого мониторинга показала, что применение в расчетах этого уравнения позволяет лучше анализировать закономерности деформаций грунта при щитовой проходке в верхних мягких и нижних твердых пластах. Осадку грунта можно уменьшить, соответствующим образом увеличив давление в грунте и давление затир-
ки. Результаты исследований могут быть использованы при строительстве тоннелей в сходных инженерно-геологических условиях.
