Abstract. The article presents the experience of using the measuring complex SI-PPM 15N1955 to determine the possibility of passing on permanent bridges of superheavy loads used by military engineers.

The first part of the article substantiates the need to examine a large number of bridges of various designs on the routes of exit and maneuver of the troops, which in turn puts before the engineering service of associations and connections serious tasks to determine the load capacity of artificial structures on roads. In the 2000s, specialists of the Military engineering Academy and the Moscow Institute of heat engineering developed a unified method for determining the bearing capacity of reinforced concrete beam bridges, which was implemented by STC «Technical diagnostics and precision measurements» in a portable measurement system to check the permanent bridges SI-PPM 15N1955.

The basis for the creation of SI-PPM is the calculation and experimental method of operational (on-site testing) determination of the state of the load-bearing structures of permanent bridges, using multi-channel measurements of angular and corresponding vertical movements of various sections of the main beams of superstructures from the impact of mobile test load. Unlike traditional methods of measuring deflections unacceptable in complexity and time of the survey of permanent bridges for the passage of modern missile systems.

The main part of the article describes the measurement system.

The bearing capacity of a particular bridge span is determined in the calculation program «Bridge» (the structure is presented in the article), which is part of the system. To determine the possibility of skipping the unit for a specific span of the bridge, the calculation program uses the angles of rotation of the main beams of the bridge near the supports from the impact of the mobile test load on the span, the arrangement of the wheels and the weight on the axes for the test load and the unit as the initial data. To learn how to operate the measuring system SI-MRP developed program simulator.
