Description

technical field [0001] The invention relates to the technical field of earthwork measurement and calculation, in particular to an earthwork calculation method and device that can distinguish soil quality. Background technique [0002] Earthwork is one of the main projects in construction engineering, including the excavation, filling, transportation, drainage and precipitation of all earth (stone) works. Among them, the construction cost of the project is controlled by the soil type, and the impact is significant. Therefore, in the development of earthworks, it is necessary to calculate the excavation volume according to various soil properties, so as to provide a reference basis for the calculation of earthwork volume. [0003] The traditional method of carrying out earthwork calculation mainly relies on on-site observation and sampling. This method cannot directly realize the classification and output of the excavation engineering volume of each soil quality, and it is di...

Problems solved by technology

However, this three-dimensional geological digital model is still difficult to perform earthwork calculations for differentiating soil properties, and this calculation method is inefficient or poor in robustness, and is not suitable for iterative calculations of large-scale projects or multi-period terrains

[0004] It can be seen that the traditional earthwork calculation method is difficult to calculate the earthwork according to the classification of soil quality, and the technical difficulty of the calculation according to soil quality is that when the traditional 3D graphic method performs Boolean operations on multi-period terrain, the 3D model of each soil quality Mesh quality will gradually degrade, causing technical difficulties such as tolerances

One solution is to reconstruct the 3D model, such as extracting the model point cloud, but it is difficult to ensure the conformity of the public surface of the reconstructed 3D model of each soil quality and the consistency of the key point positions

The rasterization method can solve the consistency problem, but the rasterization method has space complexity and time complexity problems. When it is applied in actual engineering, it is difficult to ensure the accuracy of the model while ensuring the computational efficiency.
