| 中文摘要: |
| 城市内的深基坑工程的周边环境通常比较敏感、复杂，存在老的浅基础建筑、构筑物和地下管线等，基坑工程的施工往往受到环境制约。这些敏感环境对基坑施工产生的变形要求要求严苛。本文以南京城区内某软土层深大基坑工程为背景，介绍了环形支撑的设计方案，结合实测数据，说明环形支撑在软土层异形深基坑中有效的保护了周边环境，取得了良好的社会效益，可为类似敏感环境条件下的软土层异形深基坑工程设计提供借鉴和参考。 |
| 英文摘要: |
| The surrounding environment of deep foundation pits in cities is often sensitive and complex. There are old shallow foundation buildings, structures and underground pipelines, etc.The construction of foundation pit works is often subject to environmental constraints.These sensitive environments require severe deformation requirements for foundation pit construction.This paper introduces the design scheme of the annular support with the background of a deep foundation pit in a soft soil layer in Nanjing urban area.Combined with the measured data, it shows that the annular support effectively protects the surrounding environment in the special deep foundation pit of the soft soil layer and made good social benefits.It can provide reference and reference for the engineering design of soft soil layer shaped deep foundation pit under similar sensitive environmental conditions. |
