摘要
拟建蒲黄榆快速路道路工程中立交主线桥某标段跨北京四环路,其中待建的8个桥墩承台基础紧邻四环主路,需沿路缘开挖10m深基坑。该主路昼夜交通流量大,在雨季施工边坡工程,应确保不影响正常交通。采用土钉墙加一道锚杆并结合微型桩的复合土钉优化设计边坡支护施工,保证了四环路道路路基基础的安全和稳定,并为相似工程提供实际经验。
A section of planed main project of Puhuangyu viaduct in Beijing is analysed due to its particularity being quite near to the original viaduct.A couple of deep foundation pits with more than 10 m deep are demanded in terms of pile construction in this new project.Also a experiential study on slope retaining project is concluded.It is typically practical for using a compound soil nail to prop lateral wall in this project in case of rainy season and normal transportation.In this paper,A experiential conclusion on Slope retaining project is drawn for similar foundation pit project.
