The application design of military use frusta beam in high frusta and big across sprinkling box beam

This paper introduces the characteristics and the flexible assembling structure form of the 83-type light military pier with the design,installation and use of the SPZ1100/40 type railway box girder bridge-assembling machine for the Fu River Bridge of the Zhejiang-Jiangxi Railway as a practical example to illustrate.

The application of military beam technique in the construction of underground station;

With an example of pinhole deflection calculation of Type 64 military beam,the paper gives a simple method using finite element analysis software to calculate the deflection of pinhole structure.

This paper expounds the components and working principles of the beam for military purpose, introduces the calculation of the flexivity generated by the construction load, and probes into the application and promotion of the technology of the military beam.

Reliability method and subentry coefficients of fatigue design for military bridge;

With the characteristics of military bridges taken into account, the dynamical relationships between the vehicle and the military bridges are studied from the angle of forced vibration of military bridges in the paper, with the factors influencing the impact coefficients of military bridges obtained.

Based on the advantage of composite materials in the military bridge equipment,several application examples in foreign countries are introduced in the paper.

In this paper,the computation principle and method of Pin-hole displacementcorrelated with load for military girder structure system are presented.

On the basis of analysis of military girder structural system,principle of its auto-matic division is researched and computer program is worked out.
