Abstract: Driven by both climate change and urbanization, extreme rainfall events are becoming more frequent and having an increasing impact on urban commuting. Using hourly rainfall data and “metro” origin–destination (OD) flow ...

Abstract: Using a suitable shield auxiliary construction method (SACM) is crucial when encountering adverse geological conditions in tunneling. However, its current selection often relies on the experience of the project team and ...

Abstract: Earth pressure balance (EPB) shield tunneling in coastal silty clay strata often faces the problems of clogging on the screw conveyor or the belt conveyor due to lumps of clay soils formed because of the large cohesion of ...

Abstract: Excavation damage induced by the drill-and-blast method (DBM) of the surrounding rock zone in tunneling intensifies the loss of groundwater and causes serious hydroecological imbalance. Traditional theoretical analysis ...

Abstract: Energy conservation is important in this modern era because of its high demand in transportation systems coupled with the depletion of fossil fuels. Biodiesel is thus an alternative fuel to replace conventional diesel. ...
