Problems solved by technology

At present, the technical specifications of the industry do not have clear indicators and evaluation methods for the technical status assessment of spur dikes. Scholars at home and abroad seldom consider the technical status assessment of spur dikes through quantification, which is highly subjective and affects the evaluation results.
The above deficiencies have affected the evaluation of the technical status of spur dikes

Embodiment 1

[0101] Such as figure 2 As shown, the evaluation method for the technical status of spur dikes in this embodiment is used for the technical status evaluation of spur dike A in 2010 on a certain waterway. The evaluation content is as follows:

[0102] (1) Dam surface: The position and elevation of the lowest elevation of the dam body and the hook head section have been collected. Compared with the elevation at the time of completion, the change is not large, and the elevation is generally above 6m. Therefore, D=1, E=1, and the calculation can be obtained R=0. (R value calculation results refer to Table 6)

[0103] (2) Slope surface: According to the technical evaluation report in 2010 and the collection of the technical conditions of the upstream and downstream surfaces of the slope, the slope surface is not greatly damaged, so D=1, E=1, and R=0 can be calculated . (R value calculation results refer to Table 6)

[0104] (3) Dam root: According to the collected data, there...

Abstract

The invention discloses an evaluation method for spur dike technical conditions. The evaluation method comprises the following steps: the graded quantitative evaluation is performed on aerial survey results based on acquired spur dike technical condition indexes according to the damage degree, the damage extent and the reflection of the damage on overall structure; D values, E values and R valuesare evaluated by four grades; the four grades are represented by 1-4 in sequence; and finally, evaluation results are recorded in an evaluation record chart. The spur dike technical conditions are quantitatively evaluated based on termly aerial survey inspection of spur dikes, so that the subjectivity of inspectors is reduced, the evaluation result information is comprehensive, and the evaluationresults are more reasonable; needed technical condition indexes are only needed to check, so that the aerial survey work is simplified; for the spur dikes with excellent technical conditions, the description can be simplified, the date input can be reduced and simplified, and the technical condition report can be simplified; and the method also can be used for evaluating the spur dike technical conditions.

Description

technical field [0001] The invention belongs to the evaluation technology of waterway regulation buildings, and in particular relates to an evaluation method for the technical status of spur dikes. Background technique [0002] Due to the influence of factors such as flow and sediment dynamics, environment, materials, structures, human activities and maintenance management, spur dikes often suffer from water damage and damage, and the coupling effect caused by flow and sediment dynamic factors is particularly obvious for the damage to remediation buildings. Therefore, it is necessary to evaluate the technical status of the spur dike, grasp the current state of the spur dike, and maintain the damaged spur dike in time so that it can continue to perform its functions. [0003] At present, the evaluation of the technical status of spur dikes is often based on the "Maintenance and Management Measures for Buildings for the Regulation of Yangtze River Trunk Channels" (May 2013), "...
