摘要
已建成的城市快速通道,由于桥头地段沉差较大,所以桥头跳车严重。分析了桥头搭板设计引起跳车的原因。通过对鄂尔多斯市城市快速通道桥头搭板的从2条缝改为1条缝、设置挤密桩和枕梁等改进设计,使跳车现象明显改观。工程应用证明改进的桥头搭板设计是成功的。
The urban rapid track appeared bumping at bridge-head heavily because of large different settlement values. The reason of bumping accused by approach slab design was analyzed by the author firstly. According to a project case of the urban rapid track approach slab changed from 2 joints to single one in Erdos, arranging the compaction pile and sleeper beam could improve the bumping obviously. The application of the case proved it successful for the improved approach slab design.
