Construction method for controlling deformation of extra-large deep foundation pit close to subway
The invention relates to the field of foundation pit construction, in particular to a construction method for controlling deformation of a super-large deep foundation pit close to a metro, which comprises the following steps that the super-large deep foundation pit to be excavated is divided into a strip-shaped foundation pit area, a soil retaining area and a large foundation pit area, and the strip-shaped foundation pit area is close to the metro; excavating on the large foundation pit area to form a large foundation pit; before the strip-shaped foundation pit area is excavated, an inclined support is preset in the soil retaining area, and the strip-shaped foundation pit area is excavated to form a strip-shaped foundation pit; and the soil remaining area is excavated, and the large foundation pit, the strip-shaped foundation pit and the excavated soil remaining area form the super-large deep foundation pit. According to the application, the soil retaining area is arranged and the inclined support is preset in the soil retaining area, so that the deformation of the foundation pit in the construction stage of the foundation pit can be effectively relieved.
本申请涉及基坑施工领域，尤其涉及一种临近地铁超大深基坑控制基坑变形的施工方法，包括以下步骤：将待挖的超大深基坑分为条形基坑区、留土区和大基坑区，条形基坑区紧邻地铁；在大基坑区上开挖形成大基坑；在对条形基坑区开挖前，在留土区内预设斜向支撑，对条形基坑区进行开挖形成条形基坑；对留土区进行开挖，大基坑、条形基坑以及开挖后的留土区形成超大深基坑。本申请通过设置留土区以及在留土区内预设斜向支撑，从而可以有效缓解基坑施工阶段的基坑变形。
