本文介绍了日本有关土壤挖掘和利用的三个专题。首先，介绍了挖掘土产生和再利用的现状。由于近年来自然污染一直是一个令人关注的问题，已经进行了几项努力，包括实验研究，以评估这些材料的环境适宜性。第二，环境岩土工程的可追溯性正在成为一个重要的考虑因素。其中一个联合项目利用盾构隧道开挖产生的土壤作为填海土壤材料，利用电子收费系统(ETC)跟踪土壤材料。第三，需要利用从2011年日本东部地震和海啸产生的灾难碎片混合物中获得的恢复土壤。讨论了从废旧混合料中提取土的适当处理以及在土工应用中利用这些土的若干问题。
Abstract Three topics on the excavation and utilization of soils in Japan are presented in this paper. First, the current status of the generation and reuse of excavated soils is presented. Since natural contamination has been a concern in recent years, several efforts including experimental studies to evaluate the environmental suitability of these materials have been conducted. Second, traceability in environmental geotechnics is becoming an important consideration. One joint project, in which the excavated soils generated from shield tunnel excavation are utilized as a soil material for reclamation, utilizes the electronic toll collection (ETC) system to track the soil materials. Third, the utilization of recovered soils obtained from disaster debris mixtures generated by the 2011 East Japan earthquake and tsunami is required. Several issues on the proper treatment to obtain the soils from waste mixture and to utilize these soils in geotechnical applications are discussed.
