Measurement method of seepage flow movement rule

Abstract

The invention relates to a measurement method of a seepage flow movement rule and belongs to the field of research on basic theory of natural science and vadose zone hydrology. The method comprises the following steps: carrying out field measurement of seepage-in flow and seepage-out flow of stressed section, downstream water level height of the section, upstream water level height of the section, downstream water level distribution area of the section, seepage-out and seepage-in section areas, virtual degree or solidity of the section; then building a relation equation among the quantities according to an opposite and uniform action rule equation set; and finally solving unknown quantities via an equation solving method so as to achieve the purpose of solving practical problems or prediction problems. The measurement method of the seepage flow movement rule has the beneficial effects of showing the theory, the formula and the method for researching, calculating and measuring the seepage flow rule, which conform with the objective laws, enabling the scientific research, experiment and actual measurement of the seepage flow to really embark on a scientific, systematic, theoretical, practical and programmed way, ensuring that the measurement work of the seepage flow rule is not detoured again, and saving manpower, material resources and financial resources.

Description

technical field [0001] The invention relates to a method for measuring the law of seepage motion, which belongs to the fields of basic theory of natural science and seepage study. Background technique [0002] The seepage mechanics system was first produced in the 1850s. In 1856, French engineer Darcy announced his famous experiment and law: the linear law of water seepage through a uniform sand layer - Darcy's law, and seepage theory began to emerge and develop. In the early stage of classical seepage theory, seepage mechanics began to develop mainly based on the needs of groundwater development, water conservancy and hydraulic engineering construction. Since the 1920s, it has been applied in the oil and gas development industry. At this stage, the factors considered in seepage mechanics are relatively simple: homogeneous porous media, single-phase Newtonian fluid, and isothermal seepage process, without considering the complex physical processes and chemical reactions in...

Problems solved by technology

[0003] Both the classic seepage hypothesis and the contemporary seepage system have the same fatal flaw: insufficient understanding of the relationship between seepage movement and its controlling factors

For this reason, the author has proved through repeated research and experiments that the exponential and binomial expressions of the modified Darcy's law are not derived from the basic theory of natural development and evolution laws, but are also based on the introduction of parameters in experiments and mechanics. The functional formula does not fundamentally solve the unscientific problem of Darcy's law, and it also gives a formula that is inconsistent with the objective
