Abstract


Large number of dangerous embankment dam reservoir , arduous task of reinforcement , the country has gradually accelerated the pace of dam reinforcement , but the reinforcement effect in the end , how to quantify their evaluation is very difficult to operate . To establish an effective the dam reinforcement effect quantitative evaluation system has become an urgent need to study the subject of water conservancy . In this paper, on the basis of the traditional dam safety evaluation technology , to establish a quantitative evaluation system of dam safety evaluation of quantitative evaluation of the system as well as the earth dam reinforcement effect . Quantitative evaluation for the quantitative evaluation of dam safety as well as the reinforcement effect provides a simple and effective evaluation index system and evaluation methods , quantitative evaluation method for dam safety evaluation and reinforcement effect evaluation guidance , has a very important practical significance . Specifically , this article is mainly carried out six tasks : (1) starting from the existing dam safety evaluation techniques , detailed analysis of the various factors affecting the impact of dam safety , dam safety evaluation quantified Evaluation Index System . (2 ) current dam safety appraisal based from the corresponding norms , existing methods , human mental activity and other aspects to determine the security level of the dam from the three divided into five , and each evaluation indicators of the safety level of evaluation criteria. ( 3) scoring method , and evolution of the quantitative evaluation model based on the degree of development of dam safety , the completion of a qualitative evaluation - quantify the conversion , to achieve a quantitative evaluation of the dam safety evaluation . (4) using the linear weighted method , compared two different methods to determine the evaluation index weight coefficient , has established a relatively complete set of quantitative evaluation system of dam safety evaluation . (5) Based on the quantitative evaluation of dam safety evaluation system , establish the earth dam reinforcement effect quantitative evaluation system . ( 6) by an example , to dam safety quantitative evaluation and reinforcement effect quantitative evaluation system and process to fully illustrate the operability of this method , the feasibility and practicality .
