Abstract

Disclosed is a method for simulating the influence on seepage by boundary water flow and a seepage apparatus thereof, which apply the axial symmetry characteristic of ring pillar soil sample seepage, combine the pipe flow theory and adopt a pipe flow mode to provide boundary water flow conditions for soil mass seepage on the basis of the traditional seepage theory, and can reappear the action of the boundary water flow process on seepage and reveal the action law and mechanism. Different pipe flow rates represent different boundary water flow conditions according to the flow rate distribution law and flow state change characteristic of pipe flow. The seepage size and boundary water flow conditions are all continuous and adjustable, and the influence on seepage by the boundary water flow can be researched quantitatively. The method and device have advantages of simple implementation and convenient operation.

Description

technical field

[0001] The invention relates to a soil mechanical seepage test method, in particular to an experimental device for simulating the effect of boundary water flow on seepage, and belongs to the field of hydraulic engineering. Background technique

[0002] As early as 1856, French engineer Darcy (Darcy) proposed Darcy's law of linear seepage. In 1889, Zhukovsky in Russia first derived the differential equation of seepage. In 1922, Pavlovsky proposed the electrical simulation method to solve the seepage field. Since the differential equation of seepage is difficult to obtain its analytical solution under complex boundary conditions, people try to solve it with numerical algorithms. In 1910, L.F.Richardson first proposed the finite difference method. After the 1960s, due to the rapid development of computer and computing technology, people widely used finite element method, boundary element method and many other calculation methods to calculate and solve seepage...
