S100: obtaining topographic survey data and raw borehole data;
s110: creating a terrain curved surface according to the terrain measurement data;
in this embodiment, the topographic survey data is input into the Civil 3D software, and the creation of the topographic surface is accomplished using the surface creation function of the Civil 3D software.
S120: connecting the drill holes on the same exploration line according to the original drill hole data to generate a geological layer drill hole connecting line;
in this embodiment, the original borehole data is analyzed to obtain the borehole coordinates and elevation information required for the formation of the geological formation surface by analyzing the sampling depth of the original borehole data, integrating the original borehole data into the Civil 3D, connecting the boreholes on the same exploration line, and converting the borehole connection into the Civil 3D route.

S140: performing interpolation operation on the original drilling data and the slope change points by using a Kriging spatial interpolation algorithm to obtain second interpolation data;
because the drilling interval is larger, the original drilling data are sparse and discrete, and a data null region is often existed, and the discrete original drilling data and variable slope point data are processed by utilizing the Kriging spatial interpolation algorithm carried by Surfer software, so that the geological layer data null region is reliably filled.

and extracting a physical function based on the Civil 3D curved surface, and vertically defining the generated geological layer curved surface to the topographic curved surface to obtain the construction of the geological layer three-dimensional model.
S170: exporting the geological layer model to generate a model file;
and the geological layer model is exported to be a model file, and the model file is put into a shared space, so that related staff can be opened for use, and the cooperative work of multiple persons is realized.
S180: and judging whether the modification authority exists, if so, executing the step of file verification, and generating a file cooperation number.
In the use process of the model file, the model file can be modified according to actual needs, and under the condition of cooperative work of multiple people, if the model file is modified by mistake, other people can obtain the wrong model file, so that wrong working results are caused.
After the model file is created or modified, if the modification is approved by team responsible personnel, the modification authority is obtained, and after the modification authority is available, the step of file verification can be executed, and the file cooperation number is regenerated, otherwise, the file cooperation number cannot be regenerated. Therefore, when the model file is opened again after being closed, whether the model file is modified by mistake can be judged by checking the file cooperation number, so that the file recovery operation can be conveniently and timely carried out, and the correctness of the model file under the condition of multi-person cooperation is ensured.
Further, as shown in FIG. 2, the step S180 of performing the file verification includes
S181: obtaining a file number corresponding to the model file, and generating a file check code according to the model file and the file number;
s182: and adding the file check code to the tail of the file number to generate a file cooperation number.
In the collaborative management system, a large number of files exist, the files are numbered by adopting a general rule, and the file numbers are generated, so that a plurality of files can be managed conveniently. The check code is added on the basis of the original file number to generate the file cooperation number, so that the operation is simple and easy to realize; the generation of the check code is related to the model file, any modification of the model file can be reflected in the check code, and the modification condition of the file can be found in time through checking the check code.

the used number area is used for storing a file number one, the file number one represents a used file number,
the unused number area is used for storing a file number two, and the file number two represents an unused file number.
After the file number adopts the general rule number, the file number is prestored in a computer and is taken from an unused number area when needed. The used file numbers are transferred to the used number area in time, so that the file numbers are prevented from being reused.
Further, the file number is composed of N numbers, and as shown in FIG. 3, the step S181 of generating a file check code from the model file and the file number includes
S1811: outputting a file number II from the unused storage area, assigning the file number II to the file number, and placing the file number II in the used number area;
s1812: calculating a hash value of the model file, wherein the hash value comprises a plurality of numbers and characters;
the hash value generated contains 64 digits and characters using the SHA-256 algorithm.
S1813: all numbers in the hash value are taken out, and a first array a containing L members is generated;
s1814: if L.gtoreq.N, a first factor x is calculated,
x＝[L/N]
wherein N is the digital length of the file code, and the first factor x is the integer part of L divided by N;
from the first array a and the first factor x, a second array b is obtained, in particular
b[i]＝a[x*i]
Wherein i=0, 1..n;
the above operation achieves uniform sampling of hash values.
S1815: converting the format of the file number to obtain a third array c;
specifically, the first digit in the file number is placed in c 0, the second digit is placed in c 1, and so on.
S1816: obtaining a file check code according to the third array c and the second array b, specifically
sum_count＝c[0]*b[0]+c[0]*b[0]+...c[N-1]*b[N-1]
check_code＝sum_count％N；
Where check_code is the value of the file check code, sum_count% N represents the sum_count's remainder operation on N, where% represents the remainder function. .
The hash value can reflect the tiny change of the model file, and the embodiment takes out partial data and file codes from the hash value to operate so as to obtain the check code, so that the check code can reflect the tiny change of the model file, and is convenient for finding out the error modification operation of the model file in time.
According to practical needs, the length of the file code is generally 8-12 numbers, the total number of numbers and characters in the hash value is 64, the second array b is generated by extracting the number part in the hash value and uniformly sampling the number part, and then the third array c corresponding to the file number is used for operation, so that the operation process is simplified on the basis of ensuring the verification accuracy.
Further, step S181 also includes
S1817: if L < N, then all numbers and M characters in the hash value are taken out, m=n-L, generating a fourth array d containing N members, specifically
Fetching all characters in the hash value, generating a fifth array e,
m characters in the fifth array e are taken out to generate a sixth array f
f[j]＝e[3j]
Wherein, j=0, 1..m,
the steps realize that partial characters in the hash value are uniformly extracted.
Generating a fourth array d according to the first array and the sixth array
d[k]＝a[k]，
Wherein k=0, 1..l,
d[L+j]＝f[j]
wherein, j=0, 1..m,
the above steps realize the expansion of the first array a.
S1818: obtaining a file check code according to the third array c and the fourth array d, specifically
sum_count＝c[0]*d[0]+c[0]*d[0]+...c[N-1]*d[N-1]
check_code＝sum_count％N；
Where check_code represents the value of the file check code, sum_count% N represents the sum_count's remainder operation on N, where% represents the remainder function.
If the length L of the digital part in the hash value is smaller than the length N of the file number, part of characters in the hash value are extracted uniformly, the first array a is expanded to obtain a fourth array d, and the third array c and the fourth array d are used for operation to obtain a check code, so that the accurate calculation of the check code under the condition that L is less than N is realized.
