Calculation method applicable to sliding resistance of anchor piles

Abstract

The invention discloses a calculation method applicable to the sliding resistance of anchor piles. The calculation method applicable to the sliding resistance of the anchor piles disclosed by the invention can be used for design calculation of a single row of anchor piles, such that the minimum sliding resistance and the best pile arrangement position can be obtained; and the calculation method also can be used for optimal design calculation of multiple (double) rows of piles. Due to engineering project comparison, the result shows that a matrix array method is more scientific than the traditional method; and the calculation result is more reliable and reasonable in a major landslide prevention and treatment engineering if the matrix array method is combined with a finite element method.

Description

technical field [0001] The invention relates to the field of anti-sliding resistance of anchor piles, in particular to a calculation method suitable for anti-sliding resistance of anchor piles. Background technique [0002] Slope is the most common geological environment in human engineering activities, and landslide disaster is one of the main forms of geological disasters. There are many prevention and control measures for landslide disasters, and anchor piles are widely used in landslide control because of their strong anti-slide ability, flexible pile design, and safe and convenient construction. In the landslide prevention and control engineering design of anchor piles, the landslide thrust borne by anchor piles is the key to the design of engineering piles. Aiming at this problem, many scientific and technological workers have carried out some researches and obtained some results. At present, there are mainly two theoretical calculation methods for the calculation of...

Problems solved by technology

One method is to design according to the cantilever pile, and the design residual sliding force corresponding to the location of the anchor pile (attached figure 1 Curve B in the magnitude ) as anti-sliding resistance, without considering the resistance of the soil in front of the pile, this scheme is relatively safe and suitable for the design of cantilever piles, but for buried piles, the anti-sliding resistance calculated by this scheme is too large, causing engineering waste; the second method is to convert the residual sliding force curve (attached figure 1 ) in the difference between curve B and curve A ( - ) as anti-sliding resistance, although this scheme considers the resistance of the soil in front of the pile, it also has its own defects (will be analyzed later), and it cannot be used for the design calculation of double or multi-row anchor piles
