Abstract

Arched bridges with suspension brackets of cables are built over the river Ohta in Saint Petersburg and the river Ishim in Astana (Kazakhstan). Each semi-arch was carried  out  of  separate units from supporting block of the arch tightening. There are given the formulas for calculating the precision of semi-arch jointing depending on the fabrication accuracy and dimensions of its elements, on the shape and size of the arch  span. Calculation  examples  are given for the arch bridge construction over the river Ishim in   Astana.
