Studies On Evaluation Of Formwork Construction Based On Green Concept

The extensive development of China's construction industry has caused the problem of excessive consumption of resources and environmental pollution.The green construction industry has gradually promoted with the guidance of green concept Green construction is essential with the characteristics of long construction period,high cost and large energy consumption,controllable consumption of resources and energy,whereas research about green construction formwork engineering is limited so far.To improve the level of green construction of template engineering,the evaluation of the template engineering construction based on the green concept,the main work and research results are:(1)Collecting the indicators of green construction evaluation,found the non-green factors of the formwork construction and built the green construction evaluation index set of the formwork engineering;through questionnaire survey to selection of indicators for template engineering experts and construction site technicians,and reliability and validity were tested with SPSS software,the green construction evaluation index system of template engineering was obtained,it have 21 quantitative indicators and 9 qualitative indicators for green construction in the template engineering stage.After that,by explaining the source of the evaluation indicators and the actual application,and referring the relevant specifications and the experience of the construction technicians,the grading standards for quantitative and qualitative indicators were set separately.(2)The comprehensive integration method combining improved AHP and entropy weight method is used to determine the weight to eliminate of the influence of subjective and objective factors;then analyzes and compares the commonly evaluation methods and the applicability of fuzzy matter-element analysis to the green construction evaluation of formwork engineering is illustrated,and the evaluation model of green construction of formwork engineering is established.It was found that 12 indicators in the evaluation index are directly related to the type of building template and the weight is 60.37% of the total weight.The performance of the commonly used building formwork is sorted by AHP-TOPSIS method to obtain plastic.It shows that green performance of the plastic template is optimal and the plywood is the worst.(3)Case analysis.The assessment model established in this paper is applied to the Taoyuan Yifang reform project which using plastic template.The evaluation results show that the green template construction fuzzy matter element analysis evaluation model is operability and also confirms the great effect of plastic template in practical applications.
