Abstract: AbstractDuring earth pressure balance (EPB) shield tunneling in clayey strata, issues such as clogging at the cutterhead and screw conveyor are common. The combination of foam and dispersant has been shown to effectively ...

Abstract: Expansive soils in cut slopes are prone to sliding for a period of time after excavation. They are commonly found during construction in expansive soil subgrade. Their sliding is not directly affected by the height and ...

Abstract: In this paper, safety evaluation for tunnels through steeply inclined strata in cold regions is proposed, for evaluating the safety of lining structures with existing or underlying frost heave damage. Laboratory model tests ...

Abstract: AbstractSoil conditioning is one of the essential methods to ensure the stability of the tunneling face and excavation efficiency in EPB construction. Existing commonly used soil conditioners include foam, bentonite slurry, ...

Abstract: ontinuous eddy covariance measurements of CO2, water vapor, and heat fluxes were obtained from a maize field within an oasis in northwest China from 1 May 2008 to 30 April 2009. The experimental setup used was shown to ...
