Description

Technical Field

[0002] Water conservancy project construction projects are large in scale and involve many disciplines. In engineering construction, the reservoir basin, as an important component, plays a vital role in the successful implementation and long-term operation of the entire project. When designing the project, relevant laws, regulations and standards should be followed, and various factors, including geological conditions, climatic conditions, water resources, etc., should be fully considered to ensure the quality and safety of the project. By creating a digital engineering model of the reservoir basin, integrating and applying it throughout the entire process of planning, surveying, design, construction, and operation and maintenance, and realizing data sharing and information management throughout the life cycle of the engineering construction project, it will surely play an important role in the high-quality development of the water conservancy industry.

[0003] At present, in the process of creating digital engineering models of reservoir basins, due to the uneven level of creators, the efficiency of manually created digital engineering models is low, and the digital engineering model information is seriously missing. During the application of the whole life cycle, the information needs to be reworked many times. Water conservancy projects have a long cycle and change quickly. Changes often occur during design and construction. For example, when geological conditions and water resources change, the reservoir basin needs to be modified or even redesigned. In the past, due to the difficulty of modifying digital engineering models, the modification cycle is long, and the modification is not timely, the traditional two-dimensional drawings are delivered, which seriously affects the quality of communication between design and construction personnel.
