1. Review of the number of earthwork outside the cave: According to the original ground line data measured by the surveying engineer on site, the original ground line is drawn by AutoCAD technology (the hole section is generally designed according to the section of 5m section), and then according to the mileage pile number. The corresponding structural section forms a closed section with the original ground line, and the area of ​​the section is obtained by AutoCAD's unique function-area query command; or the multi-segment command is used to circle the closed section, and then the features in the AutoCAD software are utilized. The search function can be used to obtain the cross-sectional area; the number of earth and stone in the corresponding mileage can be obtained by using the detected cross-sectional area.
2 Because the tunnel is in different geological range of surrounding rock, its lining structure is divided into different types, and the engineering quantities of different types change accordingly. Therefore, when calculating the engineering quantity, it is necessary to use AutoCAD to draw various lining sections of the tunnel. According to the needs of the calculation, it is necessary to draw different blocks when drawing, so as to obtain the relevant data needed. Generally, the PLINE command can be used to draw the surrounding area of ​​the required area into a closed circle on the drawn picture; or the PLINE command can be used to re-write the required irregular line segment on the drawn picture, and then use AutoCAD software. The characteristic search command can obtain the area of ​​the block or the length of the irregular line segment, thereby achieving the purpose of calculating the engineering quantity of the irregular structure. The area or segment length calculated by this method is very accurate (only one of the lining modes), which can meet the calculation of engineering quantity and the establishment of engineering account.
3. AutoCAD technology and engineering quantity calculation With the improvement of the project construction equipment system, engineering data and engineering construction are required to be carried out simultaneously. The improvement of engineering data will affect the measurement of the project, the operation of the project department and the delivery of the project.
There are many hidden projects in tunnel engineering. When making materials, many hidden structures need to be attached to the corresponding quality inspection data. The traditional manual drawing has not adapted to the needs of engineering construction, and the drawing function of the office software word, excel and other software used now is much worse than the drawing function of AutoCAD software, and can not complete the drawing of complex graphics. AutoCAD software has powerful drawing capabilities and is very free to convert in word, excel and other software.
<br> <br> end with the development of CAD technology, computer-aided management is also becoming increasingly important, if content with showing a computer, can only be regarded as the initial stage of computer applications. In terms of decision management and system management, the world of computer applications is more extensive.
Looking forward to the future, the development of computer technology is endless. Each of our engineering designers will use this advanced technology as a means to exert the best capabilities in their respective positions, with dedicated service, quality construction and dedication. Spirit, we make our contribution to the construction of highway engineering and civil buildings.

The spliced Multispectral Filter uses a cut and splice method to combine multiple single-spectral filters into one multispectral filter. The difficulty of this process lies in controlling the parallelism of different channels, avoiding light leakage from the splicing gaps, and ensuring the strength and reliability of the splicing. The advantage of this technology is that it can realize the splicing of multiple spectral channels.
