Resistivity method is the important exploitation method of one of geophysical exploration, expresses ground in the form of resistivity section figure
Variation of the lower medium on horizontal and depth direction is looking for mine and is solving construction, the hydrology, engineering geological problems and environmental monitoring
In be used widely.
Due to the complexity of geological conditions, real work often faces hypsography, pendage, constructs the complexity such as violent
Situation.It is limited to the present art, electrical prospecting theory generally based on one-dimensional HORIZONTAL LAYERED MEDIUM WITH HIGH ACCURACY, does not account for reality
Under the conditions of between measuring point there are height difference, pendage rises and falls, lithology is laterally discontinuous situations such as so that resistivity section and reality
There are deviations on stratum, or even mislead to user.Therefore, to resistivity section progress layer bit correction, there is an urgent need,
The relevant technologies are widely studied.
Early stage layer bit correction problem caused by the influence of topography mainly uses ratiometric correction method.This method first passes through certain hand
Section obtains pure landform exception, and then the exception multiple caused by landform multiplies or reach divided by measured data the effect for slackening the influence of topography
Fruit.In computing capability limited early stage, the means for obtaining pure landform exception have the physical simulating methods such as sink, soil box, conductive paper,
DC electrical method is also obtained using the analytic solutions of field by conformal mapping.With the development of computer and computing technique, two peacekeepings
Three Dimensional Pure landform forward simulation becomes the another way for obtaining pure landform exception.But since actual landform rises and falls and stratum electrical property
Complexity, as near surface weathering, wind erosion, erosion the effects of so that earth's surface or near surface is generated inhomogeneities, no matter physics mould
Quasi- or numerical simulation cannot accurately simulate the truth of detecting area, therefore be difficult to obtain accurate pure landform shadow
It rings, actual production meaning cannot be obtained.

Actual measurement standard resistivity substitutes homogeneous half space resistivity in numerical simulation, proposes to obtain nothing using small pole span dc resistivity
The skin resistivity value of the influence of topography utilizes ground with homogeneous half space resistivity in actual measurement standard resistivity substitution numerical simulation
Shape influences to reduce the feature that (or early to advanced stage) gradually weakens with frequency, using rate of change between frequency point or between time road as correcting
Coefficient realizes the method that measured data carries out topographical correction that relies on.This method relies on small pole span dc resistivity and obtains earth's surface
Resistivity value, it is often and uneven due to detecting area earth's surface, it needs to encrypt collection point and field work amount is increased, and work as earth's surface
Grounding requirement cannot obtain data when bad, and making the application of this method, there are the bases that practical difficulty even loses application.
