| 摘 要： | 郑州市京广路拓宽改造及地下隧道工程第三标段采用明挖法施工，两侧修筑保通道路，由于边坡荷载较大，隧道基坑两侧采用“排桩+预应力锚索”联合支护方案。监测结果表明，联合支护方案，保证了基坑与周边建筑物的安全，同时缩减了施工工期，降低了工程造价。

| Abstract: | Both the widening and reconstruction project and the 3rd contract section of underground tunnel project of Jingguang Road in Zhengzhou adopt open excavation with roads for traffic management to be built on both sides. Due to large slope load, the combined support plan of ＂piles in row ＋ prestressed anchor cable＂ is used on two sides of the foundation pit of the tunnel. The monitoring result shows that this combined support plan not only secures the foundation pit and the structures surrounded, but also reduces the construction period and project cost. |
