ВЛИЯНИЕ ПОДЪЕМА ГРУНТОВЫХ ВОД И ОСУШЕНИЯ НА ЭФФЕКТИВНОСТЬ АНКЕРНОЙ СТЕНЫ ГЛУБОКОГО ЗАЛОЖЕНИЯ Monitoring the groundwater recharge and dewatering and its impact on efficiencies of the deep anchored wall

Аннотация


Приведена оценка изменений эффективности анкерного ограждения глубокого котлована в г.Масхад (Иран) после приостановки строительства в течение двух лет. Для борьбы с неконтролируемым подтоком воды в основании стены были установлены дрены, позволяющие снижать давление и контролировать смещение стены. Для оценки уровня грунтовых вод, смещения грунта и прилегающих сооружений в процессе строительства был проведен геотехнический мониторинг, который показал, что при глубоком подтоплении со стороны нижележащего водоносного горизонта смещение стены сохраняется в пределах проектных критериев. После осушения общая осадка за пределами котлована минимальна и находится под контролем. Мониторинг позволяет прогнозировать последствия просадок при устройстве больших и/или глубоких выработок и контролировать действующие усилия во время строительства. Результаты этого исследования могут быть использованы при выборе методов осушения и контроля за уровнем грунтовых вод при просачивании.
