State-bounded directional accumulation in post-liquefaction sand: A hypoplastic formulation for asymmetric cyclic deformation

Experiments on saturated sand show finite, bilateral post-liquefaction strain accumulation with a larger strain excursion on the triaxial-extension (TE) than on the triaxial-compression (TC) side, whereas existing constitutive treatments still struggle to reproduce this asymmetri...

Identifying ecosystem service drivers to inform land use scenario simulation: An InVEST-PLSR-PLUS framework for the Danjiangkou Reservoir Basin, China

The Danjiangkou Reservoir Basin is the core water source of the Middle Route of China's South-to-North Water Diversion Project, yet research in this basin has largely focused on static ecosystem service (ES) assessments, leaving the drivers of ES dynamics and their future traject...

Numerical Simulation for Temperature Control and Crack Prevention of Tunnel-Lining Concrete During Construction

This paper develops a three-dimensional refined finite-element model for the typical concrete lining of the Dianzhong Water Diversion Project tunnel, investigates the temperature and stress fields of the lining, and systematically analyzes the influences of various temperature-co...
