摘要
随着地铁保护区内的桩基施工项目规模越来越大,并且数量也越来越多,随之而来的是也发生了一些桩基施工对地铁隧道的结构和运行产生破坏的安全事件,那么在施工中就更应充分的认识到保护地铁隧道的必要性和重要性,针对我国很多地区存在着的受盾构扰动、降水和超挖影响的黄土地层,详细的探讨了在地铁保护区内近距离桩基施工对现场地铁隧道结构可能产生的影响,同时也针对其关键施工技术进行了介绍,并提出了有针对性的施工工艺。文章便从桩基施工对运营线路的影响研究和地铁保护区内桩基近距离施工工艺分析两方面详细的讨论了地铁保护区近距离桩基的施工工艺技术。
With the increasing scale and number of pile foundation construction projects in subway protection areas,there are some safety incidents that pile foundation construction has damaged the structure and operation of subway tunnels.then in the construction,we should be more fully aware of the necessity and importance of protecting subway tunnels,aiming at the loess strata disturbed by shield,precipitation and over-excavation in many areas of China.In this paper,the possible influence of short-distance pile foundation construction in subway protection area on the structure of subway tunnel is discussed in detail,and the key construction technology is introduced,and the targeted construction technology is put forward.In this paper,the construction technology of short-distance pile foundation in subway protection area is discussed in detail from two aspects:the influence of pile foundation construction on operation line and the analysis of short-distance construction technology of pile foundation in subway protection area.
