SUBSURFACE INVESTIGATION, SECTIONS E006 TO E008, GREENBELT ROUTE

Results are summarized of 33 test borings made along two alternative alignments studied for Sections E006 to E008 of Greenbelt Route of the Washington Metropolitan Area Metro System. The borings were positioned within planned sections of earth tunnels to delineate potential tunneling difficulties to assist the General Engineering Consultant in studies and recommendations of the optimum tunnel profile position. The report contains continuous geological sections incorporating the new borings, logs of the borings, results of laboratory tests on soil samples obtained and a discussion of anticipated construction difficulties for the alternative tunnel schemes.
