右线现浇梁线形控制论文(国外英文资料) 40 + 64 + 40) M prestressed concrete Continuous channel beam linear control Author: qi yanwu (China iron 15 group 7) Abstract: during the construction of the large span groove, the stability of the bridge is increased by using the steel structure such as the military pier and the berley frame. Bridge upper structure of the lateral steel template, outside the inner cavity mould using bamboo veneer, steel pipe frame support, using the linear monitoring and control measures, this process in the cast-in-place beam construction control got very good effect. Keywords: linear control of steel structure settlement 1 overview Southwest of taiyuan railway engineering circle across too boc right trough type continuous beam, the main line bridge plane located at R = 2000 m round curve, the main use 40 m + 64 m + 40 m across three variable cross-section continuous groove type beam structure, the continuous channel beam in curve segment, minimum radius of 2000 m. The bridge is 145.1 m, total width 10.8 m, and the inner net is 6.9 m. The span of the beam is 3.5 m, and the beam is 4.3 m high, and the beam is 5.6 m high, and the top of the beam is changed by the circle curve, the radius of the curve is 260.65 m. The wall height is 0.7 m, the base is 0.25 m, and the width is 0.2 m. The width of the longitudinal girder is 0.3 m ~ 0.4 m. The roof thickness 0.47 m, the thickness of the bed board is 0.45 m, the base of the branch is set to the beam, the height 1.25 m, the width of the branch is 1.1 m, and the width of the branch is 1.5 m. The total length of the bridge is 34.0 m, the length of the section A2 is 25.0 m, and the length of the span is 2.5m, and the length of the span is 28.05 m. FIG. 1 40m + 64m + 40m grooved Figure 2 40m + 64m + 40m groove current cast-in-place Construction considerations The monitoring and control of the stress, deformation and stability of the construction of the upper structure of the bridge are monitored and controlled.
