The invention belongs to the technical field of steel truss girder cable-stayed bridge construction in bridge engineering, in particular relating to a quick construction method of a two-tower five-span steel truss girder cable-stayed bridge. By utilizing the quick construction method, the problems that the construction is slow and the final closure mostly influences the closure precision and lineshape of the cable-stayed bridge when the symmetric cantilever method is adopting during the construction of the existing two-tower five-span steel truss girder cable-stayed bridge. The quick construction method of the two-tower five-span steel truss girder cable-stayed bridge comprises the following steps: firstly, simultaneously constructing two main tower columns by the same method, constructing the main tower columns through segmented casting, and simultaneously constructing the steel truss girder in the manner of assembling a single cantilever from side-spanning to mid-spanning through auxiliary spanning; then, carrying out the mid-spanning closure of the two main tower columns; and finally, finishing the bridge deck facility. The construction method ensures quick construction speed and is suitable for constructions of all two-tower five-span steel truss girder cable-stayed bridges.

The present invention provides a method for producing a fiber fabric, which can obtain a stiff fabric without using particularly thick yarns or producing a high-density fabric with a large load in the weaving or knitting stage, and without performing a stiffening resin process. Hand-feeling fiber cloth. The method for producing a fiber fabric of the present invention is to treat a fabric mainly composed of nylon fibers with a treatment liquid containing benzyl alcohol.

The invention discloses a prestressed concrete variable cross-section box bridge. A horizontal anchoring plate is arranged at a corresponding girder height position of a base plate at a mid-span position. An upper bending anchoring plate is arranged along a box girder from the mid-span to a pier in longitudinal direction above the horizontal anchoring plate. The upper bending anchoring plate, the horizontal anchoring plate and the base plate are integrated from the mid-span to 3L / 8 section area and are separated at other positions. A layer of prestressed base plate cables is distributed in the upper bending anchoring plate, and another layer of prestressed base plate cables is distributed inside the horizontal anchoring plate. Simultaneously, the invention further provides a construction method of the bridge. A hanging basket cast-in-cantilever method is adopted for conducting construction, the upper bending anchoring plate, the horizontal anchoring plate and a box girder section are subjected to cast-in-place cantilever construction, or the upper bending anchoring plate and the horizontal anchoring plate are delayed for a construction stage and are cast in place on a support in a box or a cradle. Excavating rate of cross section of the base plate and a flat bending range of the prestressed base plate cables are reduced, and upward radial component force of upper bending prestressed base plate cables can offset second-phase dead load and vehicle load acting force.

The invention provides a method for unbalanced load monitoring and overall stability judgment in bridge cantilever method construction, belonging to the technical field of bridge construction. This method installs strain gauges and temperature sensors on temporary consolidation columns or piers of continuous rigid frame bridges, and uses the least square method to obtain the statistical relationship between strain and temperature according to the measurement results of temperature and strain under the condition of no construction load on the bridge.
