摘要
以北京地铁6号线甜水园站附属结构工程为背景,1号风道及4号出入口基坑工程的特点是形式不规则、深浅不一、周边环境复杂。针对周边实际情况,采用分段开挖、桩撑支护与桩锚支护相结合的支护方法。充分利用以上三种方法的优势,在满足施工的基础上,保证了基坑及周边环境的安全,可为以后类似工程提供可借鉴。
Taking the subsidiary structural engineering of Tianshuiyuan Station in Beijing Metro Line No. 6 as a background, the No. 1 duct and No. 4 entrance foundation pit engineering is irregular in form, shades, and the surrounding environment is complex. According to the actual condition around, the supporting method is adopted in the combination of subsection excavation, pile support and pile anchor support. This paper made full use of the advantages of the above three methods, ensured the safety of foundation pit and the surrounding environment on the basis of meeting the construction foundation, which could be used as a reference for similar projects in the future.
