Embodiment Construction

[0023] The method for automatically drawing engineering geological histograms of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] like figure 2 Shown, the method for automatically drawing engineering geological histogram of the present invention, comprises the steps:

[0025] Using the principle of nonlinear programming, calculate the height coordinates of the optimal position of the engineering geological description text of each stratum in the drawing under the preset conditions;

[0026] Drawing the engineering geological descriptive text of each stratum on the drawing according to the height coordinates.

[0027] On the basis of the engineering geological histogram generated by the existing industry software, the layout of the engineering geological description text can be adjusted through the method of automatically drawing the engineering geological histogram of the present invention, and th...

Abstract

The invention provides a method for automatically drawing an engineering geologic histogram, comprising the following steps of: by adopting a nonlinear programming principle, calculating height coordinates of optimized positions of all stratigraphic engineering geological description words on drawings on the premise of satisfying a preset condition; and drawing all the stratigraphic engineering geological description words on the drawings based on the height coordinates. The invention further provides a system for automatically drawing the engineering geology histogram. Through the technique provided by the invention, whole-course automatic drawing can be realized, manual postprocessing to the drawings by manual power is avoided, manual processing process on the engineering geological description words in manual postprocessing is avoided, and a large amount of labor cost is saved. Moreover, the automatic degree is high in the drawing process; the processed engineering geology histogram is reasonable in the engineering geological description words distribution; the drawn engineering geology histogram has normalization and orderliness; and the method and the system disclosed by the invention are suitable for processing engineering geology histograms in various types of geological engineering and geotechnical engineering investigation, and have high efficiency and strong professionalism.

Description

technical field [0001] The invention relates to the technical fields of geological engineering and geotechnical engineering investigation, in particular to a method and system for automatically drawing engineering geological histograms. Background technique [0002] In the field of geological engineering and geotechnical engineering investigation, geological records are obtained after drilling cores. An original map compiled from the data obtained from the observation and identification, sampling analysis and various tests in the borehole. The histogram of engineering geology vividly shows the relationship between the rock formations and ore bodies passed by the drill hole, and is one of the main bases for compiling other comprehensive maps such as engineering geological profiles and calculating mineral reserves. The existing national standard "Code for Geotechnical Engineering Investigation GB50021" clearly requires that the geotechnical engineering investigation report sh...
