In this paper, Three-dimensional (3D) numerical simulations are carried out to compare the construction methods for an excavation above shield tunnels through a case history, which has been constructed by a novel excavation method, referred to as divided alternate excavation method (DAEM).
Through the comparative studies and parametric studies, suggestions are proposed for optimization of construction methods for deep excavations above shield tunnels.
Drill and blast is a major method for bedrock excavation in nuclear power plant engineering.
In the present study, a micromechanics-based continuum model of a jointed rock mass is proposed and an analysis method for underground excavation is developed.
A multi-objective inverse analysis method for slope excavation was proposed, in which orthogonal design, numerical simulation, back propagation neural network (BPNN) and elitist non-dominated sorting genetic algorithm (NSGA-II) were integrated.
After nearly 30-year practices, several safe and efficient methods for the PL excavation of dam foundation are gradually developed.
The method used by archaeologists for excavation and recording of the stratigraphic evidence, within trenches with or without archaeological remains, can potentially be useful to contaminated land consultants (CLCs).
Event type: The mass balanced method of excavation ('cut-and-fill') is commonly used for road construction on hill slope (Keller and Sherar, 2003; Cornforth, 2005).
This method of excavation neither increases nor decreases the slope stability, so the adjustment factor for F4 is given as 0. These F1, F2, F3, and F4 values were added with the RMR basic value to find the SMR values.
Petrie developed a systematic method of excavation, the principles of which he summarized in Methods and Aims in Archaeology (1904).
