Methods For Quality Control And Evaluation Of Geotechnical Engineering Survey

Geotechnical engineering survey is an integral part of civil engineering.In practical engineering,Geotechnical problems are one of the main factors affecting engineering quality.So geotechnical engineering survey plays an important role in engineering construction.To sum up,it is very important to study the quality control and evaluation methods of geotechnical survey.In view of the weak quality concept and the inability to solve the common problems of engineering quality,this paper makes a comprehensive research on the quality control and evaluation method of geotechnical engineering survey.The related quality is expounded Based on the basic theory of quantity control and evaluation method,the factors affecting the quality of geotechnical engineering survey are systematically analyzed,and the decomposition method of geotechnical engineering survey work is put forward with the help of WBS theory,Combined with the three-stage control principle,the effective measures 4M1 E influencing factors and control points are formulated.Analytic hierarchy process(AHP)is used to quantify the key factors affecting the quality of geotechnical engineering survey,and the primary and secondary relationship of quality influencing factors is clarified,which is convenient to control the key factors.The model of quality evaluation is established based on fuzzy comprehensive evaluation method,which provides a reference method for quality evaluation of geotechnical engineering survey.Combined with the three-stage quality management theory,the measures of controlling 4M1 E influencing factors are given.The study is as follows:(1)This text summarizes and analyzes the problems and quality influencing factors of geotechnical survey.Combined with the problems faced in the geotechnical survey work and its own characteristics,the factors that affect the quality control of geotechnical engineering survey “people,materials,machines,laws,environment” are analyzed.(2)Based on the work decomposition structure(WBS),the decomposition method of geotechnical survey is proposed.Under the premise of clearly defining the field and content of geotechnical engineering survey work,based on the theory of work decomposition structure(WBS),the structure with the minimum unit ofwork package is constructed,which makes the work division clear,the responsibility clear and the smooth progress.(3)Application of three-stage control principle to the quality of geotechnical engineering survey main factors 4 M1 E and quality control points in advance,in the event,after the quality control.By means of AHP hierarchy method,the weight of each influencing factor is evaluated and judged,and the key control is carried out,so that the survey work can be carried out continuously and efficiently.(4)Fuzzy comprehensive evaluation method is used to evaluate the quality of geotechnical engineering survey.This paper constructs the influencing factors and evaluation indexes of geotechnical engineering survey quality by questionnaire survey method,and uses fuzzy comprehensive evaluation method to construct the evaluation model of geotechnical engineering survey quality.(5)Using the method of quality control and evaluation in the paper to make a comprehensive analysis of the actual cases(Jinan rail transit),using the work decomposition structure(WBS)to decompose the actual engineering cases,In combination with the three-stage control principle,a specific control method is proposed.using the AHP analytic hierarchy process to clarify the weight of the factors affecting the survey quality,and using the fuzzy comprehensive evaluation method to evaluate the survey quality,the feasibility and effectiveness of the geotechnical survey quality control method and the evaluation model studied in the paper are verified.Through the research on the quality control and evaluation method of geotechnical engineering survey,it provides effective measures for the quality control of geotechnical engineering survey,and provides a method for the quality evaluation of geotechnical engineering survey,so that the results of geotechnical engineering survey are more true and accurate.Figure [5] table [18] reference [52]...
