Soil surveying and mapping method

Abstract

The invention discloses a soil surveying and mapping method which comprises the following steps that: a detector knows the existing data of to-be-measured land, inputs the existing detection data into a computer database, compares the existing detection data with measured data information, and obtains the basic data information of soil through scanning by applying a three-dimensional laser technology for many times; the basic information of the soil is inputted into the computer, a three-dimensional soil model is established, and the size and area of the land, the slope and flatness of the soil of the land, static objects and dynamic objects are calculated according to the scanning data of the soil and the three-dimensional soil model; and finally stored analysis data are used for drawing soil surveying and mapping drawings and summarizing soil data, are compared with the existing data. The method enhances the accuracy of detection data, educes measurement waste, reduces calculation engineering, enhances the efficiency, facilitates checking, comparison and modification and improves the safety of measurement personnel during measurement.

Description

technical field [0001] The invention relates to a soil surveying and mapping method. Background technique [0002] Soil surveying and mapping is one of the most important and basic surveying methods in engineering geological surveying. It uses geological and engineering geological theories to observe and describe various soil phenomena related to engineering construction in detail, so as to find out the engineering geology in the proposed construction area. The spatial distribution of conditions and the internal relationship between various elements, and reflect them truthfully on a topographic map of a certain scale according to the accuracy requirements, and compile the map with the data obtained from exploration and testing. [0003] The field work of soil surveying and mapping and construction geological catalog mainly has two parts, namely, the measurement of spatial position and the professional description of geological characteristics. Among them, the professional d...

Problems solved by technology

Among them, the professional description of geological characteristics mainly depends on the professional knowledge and on-site observation of geological personnel, and it is difficult to be replaced by equipment or other technologies in a relatively long period of time; while the measurement of spatial position can continue to improve with the update of measurement technology, The measurement efficiency is low, the measurement accuracy is low, and the staff are required to work under the excavation surface, which has a high degree of danger; the workload of image stitching and correction in the later stage is large
