Optimum design specifications of TBM cutterheads in soft ground conditions based on field data analysis
This study aims to identify optimal layout designs and specifications for maximizing the advance rate of tunnel boring machines (TBMs) in soft ground tunneling projects. Field data from numerous projects were analyzed, utilizing a database compiled by the author over the past 20 years. The paper discusses the classification of ground types, center opening types, and scraper layout designs based on the information available in the database. The major design parameters of soft ground TBM cutterheads, including average opening ratio, opening ratio along the radius, and opening width along the radius, are extracted and correlated with TBM diameter, ground type, and center opening type. The findings provide valuable insights for the design of optimal openings in soft ground excavation conditions.
期刊介绍：
Tunnelling and Underground Space Technology is an international journal which publishes authoritative articles encompassing the development of innovative uses of underground space and the results of high quality research into improved, more cost-effective techniques for the planning, geo-investigation, design, construction, operation and maintenance of underground and earth-sheltered structures. The journal provides an effective vehicle for the improved worldwide exchange of information on developments in underground technology - and the experience gained from its use - and is strongly committed to publishing papers on the interdisciplinary aspects of creating, planning, and regulating underground space.
