Three dimensional method of quickly determining reservoir bank collapse scale

Abstract

The invention relates to the hydraulic and hydroelectric engineering field, and discloses a three dimensional method of quickly determining reservoir bank collapse scale. The three dimensional method of quickly determining reservoir bank collapse scale can quickly and accurately express the bank collapse range and scale, can provide basis and support for suitability evaluation and design scheme selection for bank collapse distribution and engineering of bank collapse distribution, and at the same time can provide powerful basis for the later period of bank collapse side slope treatment and engineering treatment scheme. The three dimensional method of quickly determining reservoir bank collapse scale includes the steps: collecting an original topographic map of a reservoir bank slope; performing landform measurement on the reservoir bank collapse range, and obtaining the real topographic map of the collapsed bank range; importing the original topographic map and the real topographic map to a GOCAD three dimensional design geological platform, and respectively forming an original topographic surface and a real topographic surface; and in the GOCAD three dimensional design geological platform, through the interaction operation between the original topographic surface and the real topographic surface of the collapsed bank range, and utilizing the point, line and surface operating commands of GOCAD to construct the three dimensional space distribution form and range of the collapsed bank range. The three dimensional method of quickly determining reservoir bank collapse scale is suitable for a high dam and a large reservoir.

[0002] With the development and expansion of water conservancy and hydropower projects, high dams and large reservoirs frequently appear in the mountainous areas of southwest my country. After the reservoirs are impounded, the rock (soil) on the bank slope is subjected to internal and external geological forces, and the bank collapses. It is difficult for geological engineers to accurately identify and express For the irregular geological bodies in the above two situations, the current traditional geotechnical engineering investigation methods and means mainly use profile measurement, combined with the engineering experience of geological engineers or general laws and principles to generalize the spatial distribution of geological bodies, but When the above-mentioned non-collapsible bank surface is distributed in important engineering parts, if its boundary involves important buildings, such as resettlement reconstruction buildings, etc., simple generalization treatment cannot meet the requirements of engineering design, and the current relevant regulations and specifications do not provide for the above-mentioned situation. To the best of the knowledge of the applicant, there is no three-dimensional method to quickly determine the scale of this type of bank collapse
