摘要
悬臂式支护结构适合开挖深度在10.0 m左右的基坑工程,但对嵌固段土质和土方开挖工艺要求高。某案例通过优化施工流程和预应力技术来减少悬臂式支护结构的变形和工程造价,各项监测数据均在正常范围,取得良好效果。
The cantilever retaining structure is very suitable for the excavation of the excavation engineering at a depth of about10.0 m. The case in this paper reduces the deformation and cost of the cantilever retaining structure by optimizing the construction process and prestressing technology. All monitoring data are in the normal range,achieving good results.
