BIM parameterization-based end bearing pile length calculation method

Abstract

The invention discloses an end bearing pile length calculation method based on BIM parameterization, and the method comprises the steps: 1, taking Revit software as a parameterization implementation tool, and building a parameterization pile length measurement model; 2, the foundation top face elevation, the instance end bearing pile bottom face elevation and the pile diameter are input, the instance end bearing pile bottom face elevation WG1 is adjusted to be X1, and the reference end bearing pile bottom face elevation WG2 is adjusted to be X2; 3, the non-rock-socketed depth h1 of the instance end bearing pile and the non-rock-socketed depth h2 of the reference end bearing pile are calculated; 4, the pile length H1 of the end bearing pile of the instance is calculated; 5, calculating the pile length H2 of the reference end bearing pile; and 6, the steps 2-5 are repeated, the instance end bearing piles are sequentially arranged, the pile length of each instance end bearing pile is calculated, and a pile length statistical table of the instance end bearing piles is exported. According to the method, the length of the end bearing pile can be calculated and adjusted through known and limited parameter values, and the construction quality and the construction efficiency can be improved.

Description

technical field [0001] The invention relates to a design method for the construction of end-bearing piles, in particular to a calculation method for the length of end-bearing piles based on BIM parameterization. Background technique [0002] End-bearing piles are piles whose superstructure load is mainly borne by pile end resistance. End-bearing piles pass through weak soil layers and are driven into the bearing layer of deep solid soil or bedrock. During the construction of construction projects, for end-bearing piles, such as bored piles, the pile ends entering the bearing layer must meet the conditions: the depth of rock-socketing is 0.4 times the pile diameter and not less than 0.5m, and the pile ends of adjacent end-bearing piles are connected. The angle formed by the line and the horizontal line is not greater than 45°, and the value of the pile distance is greater than the height difference of the pile ends. In the actual project, there are many constructions of end-...

AI Technical Summary

Problems solved by technology

In the actual project, there are many constructions of end-bearing piles, and the pile length and pile distance of end-bearing piles need to be adjusted according to the condition of the bearing layer. At present, the adjustment method of end-bearing piles is adjusted after manual calculation, and the workload is very large. And it is prone to calculation errors and errors, which greatly reduces the construction quality and construction efficiency
