ESTIMATION OF GROUND PROPERTIES BASED ON A FUZZY REASONING METHOD DURING VERTICAL HOLE EXCAVATION

摘要

Ground conditions should be considered into control algorithms in order to accomplish the smooth automatic positioning control of the excavator for the Diaphragm Wall Method (DWM). In this paper, the relationships between several kinds of measurement data and SPT N-values, which is a representative of the ground condition, are investigated first, and the N-values are estimated from three kinds of input data based on the fuzzy reasoning method. The estimated N-values showed good accordance with the measured N-values.
