Solving Traffic Congestion Problems and Definition Stress-Strain State of Curvilinear Overpass Module Sector-Ring Slab

In the article we discuss the construction of curvilinear overpass module sector – ring slab. Calculation of constructive elements and studied the stress-strain state of a sector-ring. The purpose is the development of the technique and calculation for the new construction of a curvilinear overpass for reduction of traffic jams. The methods uses are mathematical analysis, method of finite elements, method of finite differences, and analytical method of relocation. The purpose of the study is calculate constructive elements of module sector – ring slab and decrease of traffic jams. Researched the bending state of the sector-ring structurally orthotropic slab of the roadway of the curvilinear module of the combined bridge crossing. The method finite difference is used to determine the bending stiffness. There were selected cross sections of the supporting elements from the condition of their strength; the rigidity of the slab with the thickness.
