Problems solved by technology

The stratum overburden thickness calculated by this method has high accuracy when the borehole spacing is small. Encryption, such as redrawing the stratum profile, is time-consuming and laborious, and the profile drawn by this method can only reflect the stratum fluctuations between the drilling holes and the drilling holes, and it is inconvenient to calculate the stratum conditions at positions other than the connection of the exploration holes

Abstract

The invention discloses a calculation method and system for the thickness of a covering layer of any stratum and a medium. The method comprises the steps of establishing a three-dimensional geologicalmodel about the stratum according to geological exploration data; importing the position coordinates needing to calculate the thickness of the stratum covering layer into the three-dimensional geologic model, and calculating the projection distance from the position coordinates to the surface of the stratum in the three-dimensional geologic model to serve as the thickness of the stratum coveringlayer of the position coordinates. According to the method, the three-dimensional geological model can be quickly and accurately established based on geological exploration data, the precision is high, the speed is high, newly added drilling exploration points can be added in real time in the construction process, the model is dynamically modified in real time, and the stratum thickness of any unknown part is analyzed and calculated by utilizing known exploration point interpolation. The method has the advantages of being high in calculation speed, high in accuracy, visual in graph, accurate in numerical value, capable of avoiding manual calculation errors and the like, and has great significance in refined construction of projects such as rock foundation construction and pile foundation construction.

Description

technical field [0001] The invention relates to the field of geological engineering, in particular to a calculation method, system and medium for the thickness of an arbitrary stratum covering layer, which can be applied to the fields of engineering exploration, pile foundation construction, rock foundation construction and the like. Background technique [0002] In the construction process of underground engineering such as foundation treatment engineering, geological survey data is an important guiding document for underground design and construction, and its stratum profile is one of its main contents. At present, domestic stratigraphic profiles usually use structural maps, and the data source for drawing them mainly depends on actual drilling data. The stratum overburden thickness calculated by this method has high accuracy when the borehole spacing is small. Encryption, such as redrawing the stratum profile, is time-consuming and laborious, and the profile drawn by thi...
