Comprehensive analysis on frost heave factors of subgrade soil in seasonally frozen ground region

Shuili Shuiyun Gongcheng Xuebao, 2019
Aiming at the roadbed frost damage of the seasonal frozen soil area around the Qinghai Lake section of Qinghai Tibet Railway, the typical distributed silty clay is collected focusing attention on the four factors: temperature, moisture, salinity, and ...

From Data to Discovery: Characterizing the Scope and Limitations of Seedling Trait Studies in the U.S. With the EPiC Database

Ecology and Evolution, Volume 16, Issue 9, September 2026.
Our systematic review of 181 published studies investigated seedling traits of native grass, forb, and shrub species across diverse environmental conditions in the continental United States. We found that most studies focused on individuals younger than 90 days old, with only 24% of studies measuring seedling traits beyond this window.

Development of a Frost Heave Test Apparatus

, 2005
Frost heave damage to roadways costs millions of dollars every year. The need for an improved understanding of the fundamental mechanisms associated with frost heave and methods for efficiently improving frost-susceptible materials prompted the ...

Frost Heave in Swedish Slab-on-Grade

, 2004
This paper discusses the risk for frost heave in modern Swedish slab-on-grade. Theoretical simulations are undertaken in order to model the frost front below the slab.

Numerical investigation of the path-dependent frost heave process in frozen rock under different freezing conditions

Journal of Rock Mechanics and Geotechnical Engineering
Frost heave in water-bearing rock masses poses significant threats to geotechnical engineering. This paper developed a novel three-dimensional (3D) frost model, based on the combined finite-discrete element method (FDEM), to investigate the frost heave ...

Sediment Characteristics and Architecture of Triangular‐Shaped Murtoos: A Test of Murtoo Formation Hypotheses

Earth Surface Processes and Landforms, Volume 51, Issue 9, September 2026.
Murtoos and murtooized terrains are new types of subglacial landforms found in the Fennoscandian Ice Sheet (FIS) and Cordilleran Ice Sheet (CIS) regions. LiDAR‐based morphometric analyses have revealed substantial morphometric diversity among murtoos and murtoo‐related landforms, while sedimentological excavations have documented a wide range of ...

Study on the Influence of Frost Heaving on Defective Pipeline Stress in Frozen Soil Zone

Shiyou jixie, 2020
To ensure the safe operation of buried pipelines in frozen soil areas in cold season, in view of the frost heave conditions of buried pipelines with corrosion defects in the Sino-Russian Mojia section, ABAQUS is used to establish a three-dimensional ...

Development of PFAS Responsive Electrolyte‐Gated Field‐Effect Transistors Using Conjugated Polymer‐Single‐Walled Carbon Nanotube Complexes

Small Methods, Volume 10, Issue 17, 9 September 2026.
Electrolyte‐gated field‐effect transistors (EGFETs) based on single‐walled carbon nanotube (SWNT) complexes functionalized with polymers bearing pendant quaternary ammonium‐containing pillar[5]arene moieties were prepared as proof‐of‐concept sensors for the detection of potassium perfluorooctanoate (PFOK).

Persistent Warming and Reduced Freshening of the Abyssal Southern Ocean

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract Antarctic Bottom Water has thinned, warmed, freshened, and spread more slowly into the global ocean since 1970. Yet, the physical drivers of these changes and their broader implications remain incompletely understood. Here we combine up‐to‐date observations (1985–2024) with ocean model simulations extending to 2050 to quantify ongoing and ...

Frost heave model calculations for the Calgary frost heave test facility

, 1985
Frost heave calculations using the Segregation Potential (SP) model and the Incremental Ice Segregation (DISR) model are compared ta the observed frost heave data from chilled pipeline sections at the Calgary Frost Heave Test Facility. Madel calculations are performed with the measured temperature gradients and measured frost depths for a range of SP ...
