Problems solved by technology
[0003] The technical problem to be solved by the present invention is: Aiming at the characteristics of deep cover layer / soil slope with loose structure, easy deformation and stable bedrock below the sliding surface or dense soil layer buried deep, a method for deep cover layer slope is proposed. The design method of shallow-buried flexible anti-slide piles for support enables the anti-slide piles to provide slope protection under the conditions of stable bedrock or dense soil buried deep, piles that cannot go deep or are uneconomical, and construction conditions that are limited. The anti-slip force required for stability reduces the disturbance to the slope, ensures the overall stability of the slope, saves engineering investment, and speeds up the construction progress

Embodiment Construction
[0022] In practical application, first determine the location of the weak sliding surface 1 according to the geological data and survey results on site, and then arrange the pile body 2 so that it goes deep below the weak sliding surface 1. The pile length depends on the burial depth of the soil layer, construction conditions and economic However, it is not necessary to be anchored in stable bedrock or compact soil layer. In fact, the anti-sliding force of the pile body 2 is mainly related to the pile length Lu above the weak sliding surface 1 and the pile length Ld below the weak sliding surface 1, as well as the strength and stress of the soil and other factors. When the soil strength is the same, when the length of the pile 2 below the weak sliding surface 1 is much longer than that above the weak sliding surface (such as figure 2 shown), the anti-slip capacity of the pile body 2 above the weak sliding surface is smaller than that of the part below the weak sliding surface...

The invention relates to a design method for a shallow-buried flexible anti-slide pile for deep covering layer slope retaining. The technical problem to be solved is to provide the design method for the shallow-buried flexible anti-slide pile for deep covering layer slope retaining, so that the anti-slide pile can provide an anti-slide force required by stabilizing a slope, reduce the interference with the slope, ensure the overall stability of the slope, save project investment and quicken construction progress. The technical scheme for solving the problem comprises the following steps of: respectively calculating the resistance of unit pile length on the upper and lower parts of a sliding weak plane according to a formula shown in the specifications; and calculating the proportional relationship between the pile length on the upper part and the pile length on the lower part of the sliding weak plane respectively according to a formula shown in the specifications. The design method of the invention is mainly used for a deep covering layer slope retaining project.
Description
technical field [0001] The invention relates to a design method of a shallow-buried flexible anti-slide pile, in particular to a design method of a shallow-buried flexible anti-slide pile used for the slope support of a deep overburden layer. protection project. Background technique [0002] Anti-slide piles are one of the important support structures widely used in slope treatment projects. The existing anti-slide piles, whether fully buried, cantilevered or buried, require a stable underside of the slope sliding surface. Bedrock or dense soil layer, pile body has sufficient rigidity and length of anchorage section. For some projects with complex terrain and geological conditions, deep overburden slopes are often encountered, and the stable bedrock or dense soil layer below the sliding surface is buried deep. layers, the length of the pile and the section of the pile body will be too large and uneconomical, and the construction will be difficult.
