ARCH RIVALS

This article reports the first use in the UK of the innovative Matiere method of arch construction, developed in France. This method has brought large savings in construction time and materials used. It is being used in the Bargoed Colliery reclamation project in Mid Glamorgan, South Wales, to construct a three-pinned precast concrete culvert of 150m length and 7m span and height. The culvert is a series of pairs of arch segments, linked by a stitch at the crown of the arch. Its foundations are in river bed sandstone, and it carries 22m of embankment fill from bed level to a road planned for a later stage of the works. Based on various design factors, an optimal parabolic geometry was defined for the arch, to minimise bending moments. The concrete thickness and required reinforcement were then designed using two-dimensional plane frame analyses, calculated using the ROBOT structural software suite, and finally checked. The arch used less than half the concrete and one third of the steel used for conventional in situ portal culvert structures. The culvert's construction time was four weeks, compared with the usual time of more than six months.
