| 摘 要： | 北京CBD地区银泰-航华地下过街通道主通道(以下简称主通道)穿越既有国贸桥南段,主通道的施工不可避免地会对邻近既有桥梁桩基产生扰动.为保证既有桥梁结构的正常使用和结构安全,对影响范围的国贸桥桩采取复合锚杆桩的保护措施,从而严格控制主通道施工引起桥梁结构的附加沉降.通过计算分析主通道的施工对既有国贸桥桥桩的影响,并结合主通道施工的实际监测资料,表明采用复合锚杆桩加固国贸桥桩基的措施是安全可靠的. |
| 关 键 词： | 复合锚杆桩 地下通道 桥梁结构 差异沉降 监测资料 |

| Abstract: | The Yintai-Hanghua underground passage in Beijing CBD area under-passes the existing south section of Guomao Bridge.Construction of the passage will inevitably affect adjacent bridge foundation.For keeping the normal operation of the bridge and the security of the bridge structure,composite bolt piles were adopted to strictly control additional settlements of the bridge caused by passage construction.Computation was carried out to clarify the effect of the passage construction on the security of the existin... |
| Keywords: | composite bolt pile underground passage bridge structure settlement difference monitoring data |
