Benefits of a 3D geological model for major tunnelling works : an example from Farringdon, east-central London, UK [PDF]
, 2012 In the design of major construction works, the better the ground conditions are known, the more control there is on the assessment of risks for construction, contract and personnel, and ultimately on final costs. Understanding of the ground conditions is

Electronic Journal of Structural Engineering, 2023 The study of rockburst criterion is the key to predict the occurrence of rockburst. Based on the energy principle, a new multi-parameter rockburst criterion (RPC) were established. The accuracy and applicability of some typical rockburst engineering examples in China were verified by using some classical rockburst criteria and the newly proposed RPC ...
