Abstract

The invention discloses a ring-shaped inner support structure design method applicable to a large deep foundation pit of any shape. According to the method, the foundation pit of any shape is dividedinto a plurality of polygonal areas, each polygonal area should be a regular polygon, or although the planes are irregular, the planes in the two directions of the foundation pit are roughly equal; and a ring-shaped inner support arranged in each polygonal area comprises a ring-shaped support, an angle support and a diagonal brace truss. According to the method, the foundation pit of any shape isdivided into a plurality of polygonal areas, and in each polygonal area, the ring-shaped support, the angle support and the diagonal brace truss are adopted to reasonably construct the ring-shaped inner support. The method solves the problems that it is difficult to arrange supports in the irregular foundation pit, and stress on the support structure is ambiguous.

Description

technical field [0001] The invention relates to the technical field of civil engineering construction, in particular to a method for designing an annular inner support structure suitable for deep and large foundation pits of any shape. Background technique [0002] With the development of urbanization, the problem of land shortage is becoming more and more prominent, and the development and utilization of underground space occupy an increasingly important position. The scale of underground space development is getting bigger and bigger, and various special-shaped deep and large foundation pits are constantly emerging, and the corresponding foundation pit support technology is required to be continuously improved to solve various engineering problems. [0003] At present, the foundation pit support technology in various deep and complex environments is constantly improving, but because these deep foundation pits are usually located in the center of the city, the shape of the ...
