Applying BIM technology to the design of high-speed railway bridge is of great significance for improving the efficiency and quality of bridge design. In order to achieve a fully diversified bridge model construction based on design It is necessary to automatically extract key parameter information for...

On January 7, 2025, Dingri County in Tibet’s Shigatse City was rocked by a 6.8-magnitude earthquake. The quake struck with a focal depth of 10 kilometers, in an area where the average altitude reaches 4,300 meters within a 5-kilometer radius of the epicenter. Drawing from detailed field investigations,...

Driven by the strategic goals of the Dual-carbon initiative, the green and low-carbon transformation of flexible converter stations in the construction of new power systems has become an inevitable trend. Incorporating environmentally friendly, energy-efficient, high-performance, and harmonious design...

The application of reclaimed water can be used as an important avenue of encouraging the utilization of wastewater resources and maintaining water ecological safety. This presented work centered on Tangxun Lake which is the biggest urban lake in Asia created an innovative coupled two-dimensional hydrodynamic...

The operational scheduling of cascaded reservoirs presents a significant challenge due to the complex landscape of conflicting objectives and stakeholder interests. Existing multi-objective decision-making methods often conflate these two distinct conflicts into a single, monolithic evaluation, which...

In light of rapid urbanization and climate change, cities are becoming more and more susceptible to flooding. This study proposes one of the few machine learning approaches incorporating green infrastructure, such as parks and permeable pavement, into how cities adapt to flooding disasters. Using historical...

This paper conducts maintenance scheme design and material performance research based on the S218 Provincial Road intersection treatment project. On the one hand, it accurately identifies the causes of pavement diseases by carrying out special inspection work such as on-site core drilling and sampling,...

The clay–silt interbedded stratum exhibits complex structural features and significant variations in soil permeability. Accumulated sediment at the pile tip and disturbance along the pile–soil interface are common problems, which often restrict the mobilization of end resistance, lead to uneven distribution...

The construction of the western tunnel inevitably encounters the problem of seismic isolation design in high-intensity seismic zones. However, the current anti-seismic calculation methods applicable to tunnel structures mostly adopt the static method and simply increase the stiffness, resulting in overly...

With the rapid development of urban rail transit and tunnel engineering, the output of shield drilling sludge is increasing year by year, posing urgent challenges for waste disposal and resource sustainability.
