Measuring the pore-water pressure within a soil mass is critical for studying its hydraulic properties. Due to the granular structure characteristics of soil, the fine particles within soil are prone to migrate with the movement of water flow. The migration of fine particles may change the distribution of the pore-water pressure, thereby altering the local structure and hydraulic properties of soil. In this study, a new method with measurable local pore pressure is introduced to capture the localized response of pore structure of soil induced by the migration of fine particles. The new method meets the sealing requirements of the latex membrane with inserted pipes under stress. Thus, the pore-water pressure transducers can be arranged along the axial and radial directions of the soil specimens to measure the pore pressure at various positions, thereby helping to study the local hydraulic properties. The global and local evolution characteristics of the soil specimens during suffusion are studied using new the method in the suffusion tests. The results show that the new method has a satisfactory response. The spatial and temporal evolution of local hydraulic conductivity reveals that the migration of fine particles along seepage path exhibits significant localization and non-uniformity.
In recent years, with the improvement of domestic comprehensive strength and technological level, more possibilities have been created for numerous fields and rapid development has been promoted in many industries.In the new era,people have a brand-new pursuit for the quality of life.Water conservancy and hydropower projects, which are closely related to people’s life, are the basic guarantee for the improvement of living quality. The economic benefits of enterprises are promoted when the scale of water conservancy and hydropower projects expands, on the other hand, the difficulty of bidding increases as more professional cooperation units are required to meet the need of higher quality. As the key part of water conservancy and hydropower projects, the effectiveness of bidding work and the reliability of bidding results have a crucial impact on the quality of water conservancy and hydropower projects.
High dam construction is continuing to develop with new requirements for intelligent dam construction. New information technology capabilities are providing paths for improved intelligent dam construction. The key to achieving safe, quality, efficient, economic, green construction projects is to integrate these new information technology capabilities into intelligent construction methods. New systems enable intelligent construction of dams and the construction of intelligent dams. This article summarizes these two paths for intelligent construction, identifies three stages in the development of intelligent construction systems for dams, and analyzes the technical characteristics, goals, theory, methods, and management models with engineering examples for each stage of the intelligent construction process. The analysis shows the relationship between intelligent dam construction and intelligent dams, the three stages of intelligent dam construction, the changes in manager thinking for solving key problems in the intelligent era, and future developments in intelligent dam construction.
