Free stationing transformation monitoring method of high-fill airport side slope unit set total station

Abstract

The invention relates to a free stationing transformation monitoring method of a high-fill airport side slope unit set total station, and is used for effectively solving the accurate monitoring problems that a high-fill airport side slope is long and narrow, is a strip shape and is linear extension, and the graph intensity is poor. The monitoring method comprises the following steps of: dividing the involved range into a first measuring region, a second measuring region and a third measuring region from large to small, and setting a control point, a monitoring point and a turning point in each measure region, wherein the position of a survey station is freely selected; establishing a control net of the whole monitoring region, carrying out substation measurement on the control points and the monitoring points in the measuring regions, establishing a posture and oriented relation between adjacent survey stations, meanwhile, realizing larger expansion in an instrument measurement range; and taking the acquired horizon angle, a vertical angle and slant distance as observed values, taking a survey station position parameter and a monitoring point coordinate as an adjustment parameter so as to carry out parameter adjustment, and obtaining the precision result of the survey station position parameter and the monitoring point coordinate. The monitoring method provided by the invention has the advantages of high measuring accuracy, flexibility and convenience, convenience for carrying and good portability.

Description

Technical field [0001] The invention relates to an airport construction project, in particular to a free station deformation monitoring method of a single total station on the slope of a high-fill airport. Background technique [0002] Due to the development of the aviation industry, the air resources are becoming more and more tense, which will inevitably lead to a certain degree of "air-definition" in the location of the airport. Due to the national land tight control policy, the airport construction will inevitably lead to the "mountain and the sea", so airport construction has to choose On poor geological foundations, such as soft soil foundations along the southeast coast and high fill foundations in the southwest and northwest mountains, airports built on such foundations are usually called high fill airports. In order to meet the design requirements of flood frequency and flood prevention level, soft soil foundations in the southeast coast usually need to be filled; high-f...

Problems solved by technology

[0011] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present invention is to provide a free station deformation monitoring method for a single total station on the slope of a high-fill airport, which can effectively solve the problem of poor measurement accuracy and cannot meet the requirements of high-fill airport slopes. The monitoring problem of the square airport slope is long and narrow, strip-like, straight-line extending, and graphic strength is poor
