Embankment–bridge transition sections (EBTSs) suffer from diverse engineering diseases that have escalated into one of the most severe issues along the Qinghai‐Tibet Railway (QTR). Nevertheless, the causes and mechanisms of engineering diseases in EBTSs remain limited. This study employed a methodological approach to conduct field surveys in the Tu...

In recent years, urban road collapse incidents have been occurring with increasing frequency, particularly in populous cities. To mitigate road collapses, geophysical prospecting plays a crucial role in urban road inspections. Ground Penetrating Radar (GPR), a non-destructive technology, is extensively employed for detecting urban road damage, with...

The Qinghai-Tibet Railway has been operating safely for 16 years in the permafrost zone and the railroad subgrade is generally stable by adopting the cooling roadbed techniques. However, settlement caused by the degradation of subgrade permafrost in the embankment-bridge transition sections (EBTS) is one of the most representative and severe distre...

Retrogressive thaw slumps (RTSs), which frequently occur in permafrost regions of the Qinghai-Tibet Plateau (QTP), China, can cause significant damage to the local surface, resulting in material losses and posing a threat to infrastructure and ecosystems in the region. However, quantitative assessment of ground ice ablation and hydrological ecosyst...

Thermokarst terrain developed acceleratingly in ice‐rich permafrost on the Qinghai‐Tibet Plateau (QTP), China, and the most dramatic among these terrain‐altering thermokarsts are retrogressive thaw slump (RTS). Although the freeze‐thaw erosion (FTE) impacts are sharply increasing on the plateau due to RTS, especially for migration of fine sediments...

Frozen soil is a kind of composite geotechnical material with significant creep properties. To develop a creep constitutive model that can consider the composite properties and internal microcosmic damage mechanism of frozen soil, it is first conceptualized as a binary medium material containing both bonded elements and frictional elements, and the...

Ice-rich permafrost in the Qinghai–Tibet Plateau (QTP), China, is becoming susceptible to thermokarst landforms, and the most dramatic among these terrain-altering landforms is retrogressive thaw slump (RTS). Concurrently, RTS development can in turn affect the eco-environment, and especially soil erosion and carbon emission, during their evolution...

The purpose of this research is to explore the feasibility of using calcium carbide residue (CCR), a by-product from acetylene gas production, as a solid alkaline activator on the strength development in CCR–Portland cement-stabilized dredged sludge (CPDS). The effects of cement content, CCR content and curing time on the strength development of CP...

thermal characteristics of tunnel in cold regions determine whether it will be affected by frost damage. Within this context, a series of key environmental factors were recorded by filed monitoring, such as temperature, wind speed and wind direction at tunnel site. The results demonstrate that environmental factors, topography and tunnel orientatio...

A deep level electric power tunnel installation, employing a trenchless technology method is described as a study case located in Shenyang city,Liaoning province in China. In addition to its technical merits,the method provided advantages in terms of social and environmental issues especially in urban area. The paper presents a stability demonstrat...

The experience of pipe jacking in sand and gravel conditions in Shenyang is limited, especially for pipes with large diameter. So, a numerical method of forecasting the jacking force during construction was put forward based on the initial jacking force, and then jacking forces calculated from numerical simulation were compared with in-situ monitor...
