Novel mountainous area pile foundation pile length calculation method and system

Abstract

The invention discloses a novel mountainous area pile foundation pile length calculation method and system, and the method comprises the steps: inserting a plurality of pile positions of to-be-calculated pile lengths into an obtained contour map of a pile end supporting layer; calculating two contour lines, closest to the pile position, of the circle center of the pile position within the search range according to the input circle center coordinates of the pile position, the point coordinates of the contour line spline curve of the bearing stratum and the search range; calculating the Z coordinate of the pile position according to the distances between the two contour lines and the pile position and the Z coordinate attributes of the two contour lines; calculating the pile length of the pile position in combination with the input pile top elevation and the depth of the bearing stratum; and finally, according to the pile positions with the same pile top elevation and the same bearing stratum depth, calculating the pile length of each pile position in batches. According to the novel mountainous area pile foundation pile length calculation method provided by the invention, the mountainous area pile foundation pile length is obtained in batches by utilizing the data of the bearing stratum contour line and the distance between the pile position and the bearing stratum contour line,and the pile length calculation efficiency and precision are improved.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to a novel pile length calculation method and system for pile foundations in mountainous areas. Background technique [0002] At present, construction of thermal power plants, waste-to-energy plants and other buildings in mountainous areas usually requires pile driving. However, the elevation of the bearing surface at the pile end will vary greatly with the terrain fluctuation, which makes the estimation and calculation of pile length difficult. Become a difficult point; the prior art usually calculates separately according to each geological borehole histogram to obtain the pile length corresponding to each borehole histogram, but this method often has the following disadvantages: [0003] 1) The amount of calculation work is very large. For the pile foundation in the power plant, there are 2000-3000 piles. If the calculation is performed for each borehole separate...

Problems solved by technology

[0003] 1) The amount of calculation work is very large. For the pile foundation in the power plant, there are 2000-3000 piles. If the calculation is performed for each borehole separately, it will take a long time and the efficiency is low;

[0004] 2) There is no data between boreholes, so it is difficult to calculate and determine the pile length between holes. It can only be calculated by interpolation between two borehole points, and this method is only applicable to one-way slopes For the actual mountainous terrain, the rock surface fluctuates greatly, and generally it is not a one-way slope, and the calculation deviation of the simple interpolation method is relatively large
