Design and calculation method for single-row pile foundation-bearing table-retaining wall combined supporting and retaining structure

Abstract

The invention discloses a design and calculation method for a single-row pile foundation-bearing table-retaining wall combined supporting and retaining structure. The combined structure is composed of four parts including a single-row pile foundation, a bearing table, a retaining wall and sawteeth, and the design and calculation method for the retaining wall, the bearing table and the pile foundation is included. A novel combined supporting and retaining structure used for thick-layer and super-thick-layer landslide masses is provided and has a better effect and higher economical efficiency compared with a manner for independently adopting an antiskid pile or a retaining wall for supporting and retaining. In addition, the calculation method for the combined structure bearing table in which foundation resistance acts in cooperation with a pile and the bearing table is provided, is closer to the real stress state of the structure compared with a calculation method adopted at present and can simply solve the deflection, the rotating angle, the shearing force and the bending moment of the bearing table, and a reliable basis is provided for project design and calculation.

Description

technical field [0001] The invention relates to a design and calculation method for a combined retaining structure, which specifically includes a combined structure composed of a single row of pile foundations, a cap, a retaining wall, and anti-skid saw teeth, and a design and calculation method for the structure. Background technique [0002] Single-row pile foundation-caps-retaining wall is a new type of retaining structure, which is composed of anti-slide piles, caps, sawtooth and retaining wall. It is difficult to bury deep foundations of river bank protective buildings. [0003] The slope reinforcement method adopts anti-slide piles, and the pile body extends to the top surface of the slide body, so the buried depth of the anti-slide piles is relatively deep, and the pile body size and bending moment value are relatively large. The combined structure replaces part of the pile length with the structural type of the cap supporting the retaining wall to bear part of the h...

Problems solved by technology

[0013] In summary, taking the treatment of landslides as an example, anti-slide piles have significant advantages in dealing with landslides in shallow and medium-thick layers, but the effect of dealing with landslides in thick and extremely thick layers is not necessarily reliable; Earth walls can only be used to deal with shallow landslides where the bearing capacity of the slide bed foundation meets the requirements
