Automatic wiring method for determining hydrogeological parameters based on optimization control point

Abstract

The invention discloses an automatic wiring method for determining hydrogeological parameters based on an optimization control point. The automatic wiring method comprises the following steps that a confined aquifer unsteady flow pumping test is performed, and then test data is obtained; on the basis of the data of the confined aquifer unsteady flow pumping test, a measured data curve and a standard curve of a wiring method are drawn, and then the automatic wiring method based on the optimization control point is given, so as to realize the fitting of the measured curve and the standard curve; and a matching point is selected to calculate the hydrogeological parameters. The novel computer automatic wiring method provided by the invention has the advantage of simplicity in man-machine interaction and is close to a basic operating mode of a traditional wiring method; all measured points are driven by the control point, and the moving times along the standard curve can be greatly reduced; equivalently, an optimal path is sought to move a measured data point, and the precision is guaranteed; and additionally, the background operating time is shortened, and the working efficiency is increased.

Description

technical field [0001] The invention relates to a method for determining hydrogeological parameters of a confined aquifer, in particular to a method for determining hydrogeological parameters such as a hydraulic conductivity coefficient and a water storage coefficient of a confined aquifer by realizing automatic wiring based on optimized control points. Background technique [0002] In recent years, with the rapid growth of my country's population and rapid economic development, the scale and speed of urban construction have never been greater, the land for urban construction has become increasingly scarce, and the development and utilization of underground space has become increasingly urgent. Underground rail transit and stations in Beijing and some coastal cities Large-scale deep foundation pit projects such as large underground shopping malls and underground parking lots emerge in endlessly. The success or failure of these deep foundation pit constructions is closely relat...

Problems solved by technology

The traditional method uses manual wiring, the steps are relatively cumbersome, and the workload is large, and the wiring is performed by visual inspection of the wiring observer, which has a large randomness, thus introducing unnecessary errors

With the development of computer technology, computer wiring mainly stayed at the stage of manual wiring in the early years, and the automatic data entry was realized through the program, but the curve fitting was still based on subjective judgment; in recent years, intelligent algorithms have emerged, such as based on The BP neural network of the line method can solve the Theis model (2010), etc., but these intelligent algorithms have lost the intuitiveness of the wiring method implementation process
