Frost heave prediction of chilled pipelines buried in unfrozen soils
, 1984 Frost heave is an important consideration in the design of buried chilled pipelines. A procedure for calculating the amount of heave under a chilled gas pipeline is presented based on a finite-difference formulation of the heat and mass transfer in ...

Disorder Driven Anisotropic Nonlinear Hall Effect in the Kagome Metal YbCo6Ge6 at Room Temperature
Advanced Science, EarlyView.The intrinsic structural disorder and short‐range correlated motifs in the kagome metal YbCo6Ge6 constitute the primary mechanism for a robust and anisotropic nonlinear Hall effect (NLHE). This effect is sustained across a wide temperature range, achieving a nonlinear responsivity of up to ∼4.5 × 10−3 m/V at 70 K, higher than known disordered and ...

Frost heave in compressible soils [PDF]
, 2010 We develop a mathematical model of frost heave in compressible soils based on a morphological instability of the ice–soil interface. The theory accounts for heave and soil consolidation,while avoiding the frozen fringe assumption.

Experimental Study on Frost Heave Behavior of Steel Fiber Improved Soil
Geofluids, 2022 The incorporation of steel fibers into the natural soil is generally considered to be a novel and effective way to reduce the amount of frost heave induced by an artificial freezing process in underground engineering.
