Measurement of soil arching above a large diameter flexible culvert

Abstract

The paper reports on the measurement of an arching effect over a large diameter flexible culvert. An arch shape culvert, 51 ft (15.5m) in span, was erected and covered by a 44 ft (13.4m) high embankment. An extensive instrumentation program was laid out in order to check the mobilization of an arching effect during construction by measuring displacements, earth pressures, and stresses in the steel. The instrumentation data indicated that a large portion of the load due to the weight of the soil above the structure was transferred to the adjacent area.

Unweaving the Threads: Territoriality, National Ownership of Land and Asylum Policy

“…Territory is filled with ideologies. 22 The most successful ideologies will conceal this fact, thereby making practices of territoriality look objective and natural. In this way, uses of territory become decoupled from the interests, needs and values they reflect and serve, and power relations are maintained.…”
