Control settlement of recharge in ultra-deep excavations under partial block effect of aquifer
Yantu gongcheng xuebao, 2021 In coastal cities in China, taking Tianjin for an example, the pressure aquifer is rather thick and buried deep. Cutting off all the aquifer will lead to high construction cost.

Analysis of ground surface settlement in anisotropic clays using XGBoost and RFR models
Journal of Rock Mechanics and Geotechnical Engineering, 2021 Excessive ground surface settlement induced by pit excavation (i.e. braced excavation) can potentially result in damage to the nearby buildings and facilities. In this paper, extensive finite element analyses have been carried out to evaluate the effects
