The invention relates to a site stratum three-dimensional geological structure model generation method for natural foundation replacement quantities calculation, for solving the defect of tedious and subjective foundation replacement quantities calculation compared to the prior art. The method comprises the following steps: preprocessing original data, collecting site exploration hole data and topographic map data, and performing interpretation preprocessing on the exploration hole data and the topographic map data; establishing an initial triangle network model, performing interpolation calculation on preprocessed data, and preliminarily generating an irregular triangle curved surface and a landform fluctuating curved surface; establishing stratum information of virtual borings, inserting the virtual borings, and fitting the stratum information of the virtual borings corresponding to a standard stratum; and generating an site three-dimensional geological structure model, through combination with curved-surface data of each stratum and the landform fluctuating curved surface, setting side restriction conditions, and generating a triangular-prism-element-based three-dimensional model. The method provided by the invention greatly improves the work efficiency and eliminates manual calculation errors.
Description
technical field [0001] The invention relates to the technical field of data processing, in particular to a method for generating a three-dimensional geological structure model of a site stratum for calculation of natural foundation replacement engineering quantities. Background technique [0002] The traditional method of calculating the amount of foundation replacement for buildings (structures) is that civil engineering designers use manual interpretation to determine the bearing layer of each foundation based on the engineering geological profile and foundation plan, and estimate the bearing layer of each foundation. According to the known design parameters, such as site design elevation, foundation buried depth, minimum foundation bearing capacity characteristic value, etc., calculate the relevant parameters of the foundation treatment engineering quantity, mainly the foundation excavation depth, replacement height and Replacement engineering quantity. [0003] The abov...
