With the rapid development of China's economy,the number of tunnel construction in high altitude area is increasing,due to the particularity of high altitude terrain conditions,(low pressure,hypoxia,low temperature,strong ultraviolet radiation,dry climate changing)and the characteristic of tunnel construction(labor intensive,cross operation,construction etc.)efficiency will be artificial and mechanical tunnel construction is affected by different degree,this problem is the tunnel engineering industry attention,the tunnel construction of high altitude systematic efficiency reduction factors imperative.Based on the cognitive mechanism of tunnel construction in high altitude area efficiency reduction factors,through the proposed adaptation control measures,reducing the efficiency and control of tunnel construction in high altitude area under different conditions,so as to improve the efficiency of construction.First of all,this paper studies the cognitive theory and the pre-,post-and post-facto control theories.Through literature review,study the impact factors of construction efficiency reduction,that is,environmental impact factors,individual factors and organizational management factors.Secondly,the mechanism of effect factors to reduce the influence of tunnel construction in high altitude area based on cognitive theory,construction workers and construction management personnel.The influence factors on cognitive environment construction,cognitive factors,cognitive factors and cognitive factors of organization and management.Then,based on the cognitive factors affecting the preparation of the initial questionnaire and expert interviews,making cognitive influencing factors formal questionnaire,according to statistical analysis of the questionnaire,the reliability and validity of SPSS18.0 test data,which verifies the availability and validity of the data.Then,the structural equation model(SEM)is constructed.On the one hand,the use of SPSS18.0 on the formal questionnaire based data for exploratory factor analysis,which is suitable for factor analysis;on the other hand,the use of basic data as the input of SEM,using IBM SPSS AMOS Version24 to run the effects of cognitive structure of Fang Chengmo factors,after two amendments,get the regression parameters of each cognitive factors as a cognitive value,the impact factors on the degree of tunnel construction efficiency reduction,and the operation result is analyzed.Finally,according to the results of SEM output,combined with before,during and after the event,control theory,put forward the tunnel construction in high altitude area efficiency reduction adaptation control measures,so as to match the construction of tunnel under different conditions,the construction control of high altitude tunnel down effect,improve the efficiency of construction of tunnel engineering in high altitude area.
