Abstract

The invention provides a seepage solving method based on conditions of seepage boundaries and a differential equation of motion. The method is characterized by comprising the following steps: step 1, accurately measuring macroscopic geometric features of a study object, and establishing a corresponding geometric feature description equation; step 2, studying seepage coefficient distribution features of the study object, and establishing seepage coefficient distribution equations of the study object in a study area; step 3, studying boundary condition flow and water head features of the study object, and establishing a corresponding boundary condition flow and water head expression equation; and step 4, selecting the water head expression equation to enable the same to meet the corresponding differential equation of motion and the flow and water head boundary condition equations, and carrying out solving for each corresponding constant coefficient. The provision of the method has a promoting action on seepage movement study and application of various built structures and natural bodies such as dams, slopes, subgrades, tunnels, roadways and culverts.

Description

technical field [0001] The invention belongs to the technical field related to seepage, civil engineering and geological engineering, etc., and specifically relates to a seepage solving method based on seepage boundaries and motion differential equation conditions. technical background [0002] The current seepage solution is often based on numerical calculation methods such as finite elements. The finite element method uses points instead of surfaces (note: for two-dimensional problems) or points for volumes (note: for three-dimensional problems)), so different sizes of Units, the calculation results are not the same; moreover, the numerical calculation adopts the linear method to solve the nonlinear problem, of course, the results of different convergence standards are not the same. However, for a confined water and diving research object with a fixed shape, its flow state should be determined, and there is currently a lack of methods for its seepage solution. Contents o...
