    Characteristics of ground settlement due to combined actions of groundwater drawdown and enclosure wall movement

    When a foundation pit is hydraulically connected with surroundings, the dewatering inside the excavation would both induce water-level decline and enclosure wall deflection, which together cause ground settlem...

    Groundwater Response to Pum** Considering Barrier Effect of Existing Underground Structure

    Existing underground structure may block the water flow or extend the seepage path, which should affect the groundwater response induced by pum**. In this study, finite element models are established by ABAQ...

    Effectiveness of a buttress wall in reducing retaining wall movement during dewatering before bulk excavation

    Retaining wall movements are often estimated from a datum at the start of soil excavation. However, recent studies indicate that significant wall movements may occur during pre-excavation dewatering. In this s...

    Countermeasures to Retaining Wall Deflection Induced by Pre-excavation Dewatering

    Pre-excavation dewatering is an important stage in deep excavation in soft ground with high groundwater level. The deformations of retaining structure and surrounding environment induced by pre-excavation dewa...

    Responses of Retaining Wall to Pre-excavation Dewatering Under Staggered Layout of Dewatering Wells

    Pre-excavation dewatering (PED) is an important stage in deep excavation in soft ground with high groundwater level. The PED-induced deformations of retaining wall and surrounding environment can reach centime...

    Distribution Patterns of Horizontal Foundation Modulus Under Pre-excavation Dewatering

    Pre-excavation dewatering (PED) can cause a significant wall deflection. How to predict this deformation is an urgent problem to be solved. The elastic foundation beam method is widely adopted to predict the w...

    Experimental and simplified model study of the development of ground settlement under hazards induced by loss of groundwater and sand

    Most catastrophic failure in underground engineering is caused by soil and water loss. However, few studies have focused on the evolution of ground deformation during such a process. In this study, model tests...
