The western mining areas of China, which are rich in coal resources, lack water resources. Large-scale and high-intensity China’s has led to the loss groundwater Underground reservoirs mines an effective means achieving protection utilization resources these areas. One important standards for safety underground reservoir a mine involves checking whether development cracks pillar dam body, under...

The Danjiangkou hydropower station is a water source project for the middle line of South-to-North Water Transfer Project in China. dam composed riverbed concrete and earth rock on both banks, with total length 3442 m. Once wrecked, it will yield disastrous consequences. Therefore, very important to evaluate safety behavior time. Based long-term short-term memory (LSTM) network, deformation pre...

Dam breaks of landslide dams are always accompanied by large numbers of casualties, a large loss of property, and negative influences on the downstream ecology and environment. This study uses the Jiadanwan landslide dam, created by the Wenchuan earthquake, as a case study example. Several laboratory experiments are carried out to analyse the dam-break mechanism of the landslide dam. The differ...

The design of a gravity dam is performed through an interactive process involving a preliminary layout of the structure followed by a stability and stress analysis. This study presents a method to define the optimal top width of gravity dam with genetic algorithm. To solve the optimization task (minimize the cost of the dam), an optimization routine based on genetic algorithms (GAs) was impleme...

Along with the development of virtual reality (VR) technology, simulation system as a new perspective of management methods and technical means in the progress of the project management plays an increasingly important role. This paper presents a Virtools-based visual simulation method and realizes a concrete dam pouring process. It proposes that the mode of the dam for a certain period could be...

The mandrel plays a vital role in metal tube bending limit improvement and high-quality achievement. For the forming process of tubes with different diameters, corresponding needs to be customized, which has disadvantages long design cycle, high manufacturing cost, low reuse rate. Therefore, novelty concept diameter adjustable (DAM) based on multi-point contact was proposed adapt processes. Sin...
