Problems solved by technology
The investigation found that the inspection results of the current transportation and management units are "fragmented", that is, the inspection results of various parts of the dam are relatively fragmented, and the inspection conclusions do not affect each other or even have no connection
Whether the current health of the dam is good, how to quickly assess the current technical status of the dam, whether some of the defects found have a significant impact on the health of the dam, whether there are intuitive and quantitative indicators to assist in the decision-making of reservoir operation and management, these issues Troubled reservoir dam operation management unit

The invention discloses a reservoir dam technical condition evaluation method, which comprises the steps of detecting / checking a dam body, a dam foundation, a dam abutment, a water conveying and draining tunnel / pipe, a spillway, a metal structure, a near-dam bank slope and a management and guarantee facility of a reservoir dam through technical equipment and technical means, and then by adopting a method of single item selection, part selection and comprehensive weighting andcombining a single direct control index, evaluating the technical condition of the reservoir dam. According to the method, seven categories including a dam body, a dam foundation, a dam abutment, a water conveying and draining tunnel (pipe), a spillway, a metal structure, a near-dam bank slope and a management and guarantee facility are selected to form a large category, wherein the reservoir dam technical condition indexes are calculated through a layered weighting method, corresponding deduction values are obtained according to the damage conditions of inspection tour, inspection and detection, and step-by-step and layered weighting is conducted. Finally, DCI* of each composition large class of the reservoir dam and DCI of the whole dam are obtained, the intact state of the reservoir dam is graded by referring to the scoring standard, and maintenance suggestions are given.
Description
technical field [0001] The invention relates to the technical field of hydraulic structure reservoir dam safety appraisal, in particular to a method for assessing the technical status of reservoir dams. Background technique [0002] At present, the safety appraisal of reservoir dams is mainly based on SL 258-2017 "Guidelines for Safety Evaluation of Reservoir Dams". As a programmatic document in the field of reservoir dam safety appraisal, this specification has guiding significance for the safety appraisal of reservoir dams. Reservoir dam safety appraisal is mainly through on-site safety inspection and investigation and analysis, to clarify the inspection location and focus, to conduct safety inspection on concrete structure, metal structure, opening and closing facilities, etc., and on this basis to carry out project quality evaluation, operation management evaluation, flood control ability Review, seepage safety evaluation, structural safety evaluation, seismic safety eva...
