内容简介：

洮儿河主河道桥施工图设计 * * 大学土木学院毕业设计摘 要长白线一级公路，洮儿河主河道中桥初步设计为330m的预应力混凝土简支T形梁桥。该桥采用并列双幅布置，左、右幅桥等长。上部为装配式全预应力钢筋混凝土简支T梁。预制T梁高2.1m，主梁间距2.0m。为降低主梁高度，减少预应力引起的上拱度，后张法预应力混凝土T梁在设计荷载下按全预应力混凝土构件设计，主梁配筋采用预应力筋和非预应力筋混合配筋。锚具采用OVM156型锚具，锚具变形钢筋回缩按3计。预制件在张拉钢绞线时混凝土的强度应达到85%以上方可张拉。下部桥墩为钢筋混凝土圆形双柱式墩，墩柱直径1.0m；桥墩基础为钻孔灌注桩基础，桩径1.2m。桥墩盖梁为连续墩盖梁，按简支梁计算盖梁内力及墩柱顶竖向反力。桩基为单排桩形式，采用正循环泥浆护壁成孔。关键词T梁 预应力 后张法 锚固 钻孔灌注桩 AbstractChang bai line level of roads, in Taoer River main channel bridge preliminary design for 330m prestressed concrete simple support T shape beambridge.This bridge uses the compound double amplitude arrangement, the left and right bridge and so on is long. Upside for assembly type entire prestressed rinforcement concrete simple support T roof beam. Prefabricated T roof beam high 2.1m, king post spacing 2.0m. In order to reduce the king post altitude, reduces the camber which the pre-stressed causes, tensioning prestressed concrete T roof beam under the design load according to the entire prestressed concrete component design, the king post matches the muscle to use the pre-stressed muscle and the non-pre-stressed muscle mixes the syngamy muscle. The anchorage uses the OVM15-6 anchorage, the anchorage deformed bar deformed reinforc bar retraction according to 3 the idea. Pre-workpiece when Zhang Lagang stranded wire the concrete intensity should achieve above 85% only then opens pulls. Lower part the bridge pier is the reinforced concrete circular distyle distyle pillar, foot stall diameter 1.0m; Pier footing for drill hole irrigation pile foundation, pile diameter 1.2m. Bridge pier Ge Liang for continual pillar Ge Liang, calculates Ge according to the simple beam the Liang endogenic force and the pillar mast top vertical reaction. Pile foundation use for single piling form, The pile foundation uses mud propects wall of main ci
