Linear adjustment method of cable-stayed suspension cable cooperative system bridge
The invention relates to a linear adjustment method for a cable-stayed and suspension cable cooperative system bridge. The length of a sling is adjusted through a sling anchoring structure arranged on a bridge deck top plate so as to adjust the line shape of a finished bridge in a suspension area. The sling anchoring structure comprises a sling, an anchor cup connected with the sling, an anchor backing plate, a bearing plate arranged opposite to the anchor backing plate, a jack arranged on the bearing plate, and a tension rod with one end penetrating through the bearing plate and the other end connected with the anchor cup. The sling is anchored on the anchor backing plate through the anchor cup; the jack is provided with a jack nut which is connected with the tensioning rod; the distance from the jack nut to the end part of the tensioning rod and the distance from the end part of the tensioning rod to the bridge deck top plate meet the requirement of sling length adjusting quantity d; when the sling needs to be tensioned, d2gt; d; when the sling needs to be released, d1gt; and d. According to the linear adjustment method for the cable-stayed and suspension cable cooperative system bridge, a sling anchoring structure capable of adjusting the length of the sling is arranged so as to adjust the line shape of the finished bridge in a suspension area, and the enough sling length can be conveniently provided during adjustment.
本申请涉及一种斜拉悬索协作体系桥的线形调整方法，通过设于桥面顶板上的吊索锚固结构调节吊索长度以调整悬吊区成桥线形；吊索锚固结构包括吊索、与吊索连接的锚杯、锚垫板、与锚垫板相对设置的承压板、设于承压板上的千斤顶、一端贯穿承压板且另一端与锚杯连接的张拉杆；吊索通过锚杯锚固于锚垫板上；千斤顶设有千斤顶螺母，千斤顶螺母与张拉杆连接；千斤顶螺母到张拉杆的端部距离及张拉杆的端部到桥面顶板的距离满足吊索长度调节量d的要求；当吊索需要张拉时，d2>d；当吊索需要放张时，d1>d。本发明提供一种斜拉悬索协作体系桥的线形调整方法，设置一种可以调节吊索长度的吊索锚固结构，以调整悬吊区成桥线形，便于调节时提供足够的吊索长度。
