  Excavation of Unconsolidated Soil Considering Impact on Surrounding Ground

  Abstract: This report discusses tunneling in an unconsolidated shallow overburden ground with measuring displacement of support and ground. The mechanism of displacement is analyzed by measured data of final converged displacement. In this study, the concept of ‘initial displacement rate’ is defined to clarify plastic and elastic behavior of the ground. Based on this concept, effectiveness of auxiliary...
