摘要
在湿陷性黄土地层中建设轨道交通工程在国内已有大量研究成果及工程案例,但轨道交通桥隧过渡段穿越大厚度湿陷性地层目前暂无工程经验可以借鉴。文章以西安北至机场城际轨道交通项目空港新城—机场(T5)区间桥隧过渡段工程实例为背景,对穿越大厚度湿陷性黄土的轨道交通桥隧过渡段的地基及结构处理开展方案研究,提出安全、可靠、经济的设计方案及处理措施,可为类似工程提供一定的参考和借鉴。
There are a large number of domestic research results and engineering cases for the construction of rail transit projects in collapsible loess area.However,there is no reference for the bridge-tunnel transition section of rail transit in very thick collapsible loess.Based on a bridge-tunnel transition section of Konggang Xincheng-Airport(T5)for Xi’an Bei to the Airport rail transit construction,the author studied the foundation and structure treatment for the bridgetunnel transition section,and put forward a safe,reliable and economical measure,which can provide some reference for similar projects.
