Abstract:

In 1983 and 1984, an exploratory tunnel was constructed as part of the geotechnical exploration program for two highway tunnels to be constructed for interstate 70 through Glenwood Canyon, Colorado. The exploratory tunnel was constructed for the purpose of obtaining construction data, and geologic and geotechnical information regarding the rock mass conditions along the tunnel alignment. The information obtained during construction of the exploratory tunnel included such construction data as rates of production, blast data, and overbreak information. Data acquired during construction were manually entered on an on-site microcomputer. The software was capable of reducing the raw data and performing a variety of analyses and sorting routines on the raw and reduced data which greatly facilitated construction monitoring and the detection of trends as the tunnel construction progressed. The as-built data, in conjunction with blasting records, were used to assess the effectiveness of blast control and blasting procedures. This technical paper describes the data collected and procedures used in the collection effort. The organization of the field data collected and the methods of analysis are also presented.
