Evaluation of Ground Properties in Deep Soil Improvement Method and its Application to Construction Automatization

As one of the studies on automatization in the deep soil improvement method, theoretical and experimental studies were carried out to develop a method to estimate soil properties in real-time during construction. In the theoretical study, the resistance acting on the improving machines from the ground was studied with soil cutting theory, and the relationship among the resistance and the ground properties was discussed. The results of the theoritical study were examined through field experiments, and a method was suggested for evaluating the values of the SPT of the ground; the N values, from information 011 the resistance acting all the machines from the ground: Applications of this soil-estimating method to automatization in the deep soil improvement method were discussed through the determination of the best operating method for the DIM machine according to the soil properties estimated by the suggested method.
