Cut-and-cover trenching in snow
Waterhouse, Robert W.
Technical ReportSummary: During 1955 and 1956 a technique was developed and tested in Greenland for making snow-arch covered trenches designed for use as subsurface military shelters and communication ways on the Ice Cap. The initial installation consisted of a trench 8 ft wide and 10 ft deep over which an arched snow cover was formed on a removable steel form system. A track-mounted Swiss snow-milling machine driven by a gasoline engine was used in both the trench-cutting and roof forming operations. Five hundred feet of covered trench was formed and instrumented to gage the time deformation and closure rate of the cavity. A sequence of photographs are included to show details of the construction technique. The appendix contains details of the snow forms.
