Research On Quality Control Of Dam Concrete Construction Based On Fuzzy Quality Profit And Loss Function

Nowadays,the number of water conservancy projects in various regions of China is increasing.Concrete dam is an important type of dam in water conservancy and hydropower projects,and occupies a high proportion in high dams.The requirements for the quality of dam concrete construction are also constantly improving.The construction quality of water conservancy project is closely related to its service life,operation safety and efficiency.This is especially true in the construction of dam concrete,if the construction quality does not meet the standard,it will bring unnecessary safety risks for the use of future projects.In the future construction process of water conservancy projects,the requirements for concrete pouring construction technology and pouring quality will gradually increase.The existing quality control related theories can no longer meet the current quality control requirements.Therefore,it is necessary to study the quality control of dam concrete construction to ensure the stability of dam concrete construction,so as to optimize the quality of dam concrete construction in water conservancy projects from the fundamental issues,so as to better reflect the application experience.Based on the review of domestic and foreign literature on dam concrete construction and mass loss,this paper takes the establishment of fuzzy mass profit and loss function as the main line of research,combines the fuzzy theory with the mass profit and loss function,establishes the fuzzy mass profit and loss model,and studies the optimal fuzzy process mean on its basis.The main work and contributions of this paper are mainly reflected in the following three aspects:(1)Based on the fuzzy theory and the theory of quality profit and loss function,the theory of fuzzy quality profit and loss is put forward,and the model of fuzzy quality profit and loss function is constructed.Based on the fuzzy quality profit and loss model,the multi fuzzy quality profit and loss model is extended;(2)Aiming at the case where the fuzzy quality characteristics obey the normal distribution,the process mean of asymmetric fuzzy quality gain and loss is studied,the fuzzy optimal process mean is found,the trend of each pair of ratios is found,and comparative analysis is performed;(3)In view of the triangular distribution of fuzzy quality characteristics,a model for the gain and loss of asymmetric fuzzy quality under the triangular distribution of some fuzzy quality characteristics affecting the construction quality of dam concrete is established.
