The active layer in permafrost region is inevitably subjected to seasonal freezing-thawing
actions. The soil freezing and thawing can change boundary conditions of the bridge pile …

Ground seasonal freezing and thawing in cold regions can alter boundary conditions of
bridge pile foundations and influence their seismic behaviors. This article describes a test …

Pile foundation with elevated cap is always applied for railway bridges in permafrost region
to minimize the thermal disturbance to vulnerable permafrost. Permafrost can influence the …

Fixed offshore platforms supported by pile foundations are always subjected to lateral cyclic
loads due to environmental conditions. In general, nonlinear pile–soil interaction is the most …

Evidences from past winter earthquakes and field experiments have shown that seasonally
frozen ground can have significant impact on the lateral performance of bridge pile …

Frozen soils, including seasonally frozen soils and perennially frozen ground, or permafrost,
exist extensively in Alaska and other cold regions. During past earthquakes, extensive …

冻土和地震是我国西部高寒高烈度地区桥梁工程建设中主要面临的两大挑战.
冻土区线路工程广泛采用桩基础桥梁, 土体冻结后会显著影响地震作用下桩 …

Ground freezing in cold areas can cause brittle damage to deep foundations during seismic
loading. This paper presents a novel solution to this problem by replacing local soil around …

Frozen soils, including both those seasonally frozen and perennially frozen, exists
extensively in Alaska and other cold regions. During past earthquakes, widespread damage …

Seasonal freezing and thawing of the active layer in permafrost can significantly alter the
seismic response of the free field. In this study, a specific laminar shear model box with a soil …
