Abstract
The article presents results of the overpass condition survey, technical survey, static tests and assessment of the structure operational reliability, a doubledecker overpass on Almaty-Kapshagai highway section in Kazakhstan. Technical survey determined the dimensions of the overpass, the camber of reinforced concrete superstructures main beams and checked the values of the overpass roadway actual transverse and longitudinal slopes. The calculation and analytical assessment of the overpass load-bearing structures, for the strength of the bending moment, are performed. Static tests of the overpass split beam superstructure of a length of 33.0m were conducted. Trucks loaded with ballast were accepted as a test load.
Highlights
The overpass is located on a straight section in the plan and on a longitudinal slope in i = 5 ‰ profile
The technical survey was conducted at three points on each main beam - in the area of the beam support sections and in the middle of its span [11]
Defects that reduce the structure operational properties were not detected during the survey
Summary
The overpass is located on a straight section in the plan and on a longitudinal slope in i = 5 ‰ profile. The longitudinal axis intersection angle of the highway overpass with the existing highway is 66 °. The bridge layout is accepted 33+33 m. The overpass length is taken along the rear edges of backwalls and according to the project is 66.917 m. The overpass dimensions, taking into account the speed change lanes are taken 17.0 + 2 x 1.0 m. 5 = 14.0 m and the safety lanes are 1.5 m each
