Predictive model for the surface settlement caused by the excavation of twin tunnels
, 2021It is of great difficulty to accurately predict the stratum deformation caused by double-track or twin-tunnel construction because of the complex coupled interaction of the two tunnels.

Peridynamics simulation of surrounding rock damage characteristics during tunnel excavation
, 2020The improved peridynamics is introduced to analyze the stability of surrounding rock in tunnel excavation process. By introducing short-range repulsive force into peridynamic equation of motion, the tensile and compression failure characteristics of rock

Observed performance of a 30.2 m deep-large basement excavation in Hangzhou soft clay
, 2021This paper firstly performed an extensive investigation of a 30.2 m basement excavation (9310 m2 in plan) in Hangzhou soft clay. The 52 m-deep diaphragm walls and six levels of concrete struts were adopted as retaining structures to reduce the ...

Excavation-induced deformation and damage evolution of deep tunnels based on a realistic stress path
, 2021The stress path during underground excavation is critical to the mechanical response of rock masses, and the excavation effects in front of a tunnel face cannot be ignored.

The most recent inspiration for stepwise carious tissue removal in 2 stages originates from the knowhow on intralesion changes in deep carious lesions. The environmental change that takes place during the first stage of carious tissue removal is aiming for the arrest of the deep lesion, by placing a temporary restoration on top of the soft carious ...
