Mechanism Analysis and Prevention of Road Damage in High-Latitude Permafrost Regions

Abstract Frost heave and thaw settlement occur widely in northern China. Environmental change has increased their occurrence. High-latitude permafrost regions have high temperature sensitivity, experience freeze–thaw settlement, and exhibit unique rheological properties. Multiple...

Collaborative Optimization of Mechanical and Alkali-Reduction Performance of Ecological Low-Alkali Porous Concrete Based on Alkalinity Gradient Regulation

Abstract Porous concrete (PC) is widely used in slope ecological restoration due to its good permeability and plantability. However, the synergistic evolution mechanism between its mechanical properties and pore alkalinity has not been systematically elucidated, which has become...
