Applications of Horizontal Characterization Techniques in Trenchless Construction

摘要: Horizontal site characterization technologies present a rapidly evolving alternative to traditional vertical investigation methods for subsurface investigations of large diameter trenchless construction projects. A state-of-the-art review horizontal tools, both currently available and under development, is presented. Additionally, rational methodology the selection deployment techniques in projects also The enables user define quantify risks involved particular project, as well evaluate degree which these can be mitigated using various techniques. proposed model demonstrated working example. paper concludes with discussion future trends this exciting new field. main conclusions drawn from work are (1) adequate information invaluable underground construction; (2) programs linear enhanced by techniques; (3) availability continuous near-continuous utilization approaches analysis representation data.
