The paper introduces some information about Harbin Metro line 1, makes the decision analysis on economies, environment, society and geological environment of Harbin Metro line 1 by some fuzzy comprehensive evaluation model, and gives the weight coefficients of indicators through analytic hierarchy process. The comprehensive evaluation result provides the basis for decision-makers during decision of metro projects.
Deformation of segment and rock is one difficult question of the subway design. When building the calculation model of the liner we mainly think about the effect on the liner of the joint and the resistance force of the earth. In this paper the joint of the model of the used model is improved and the inner force formulas for the new model are derived. At last, the derived formulas and the existing formulas are validated by Harbin Metro Line 1. According to the research result, we can know the formulas derived in the paper are credible and they have academic practical meaning for design and construction of the subway liner.
Harbin metro, the first engineering is in the process of being built. Metro tunnel is supported by reinforced concrete structure. Commonly used model is used in design of shield tunnel liner. In this paper, the habitual model is improved. The joint of model of the habitual model is improved and the endogenetic force formulas for the new model are derived. At last, the derived formulas and the existing formulas are validated by Harbin first metro. According to the research result, we can know the formulas derived in the paper are credible and they have academic practical meaning for design and construction of the subway liner.
A general fuzzy clustering analysis theory method is introduced at first, then a GAFCM algorithm and its implement steps are given. The diagnosis types of the test samples are judged by getting across the most of the Euclid pressing close degree choosing approximately principle. Practice proves that this method can be used to diagnose the diesel engine vibration faulty.
This article uses the extenics and fuzzy hierarchy analysis method,on the slope stability analysis method of uncertainty is improved.At the same time,on the measured data report AnTaiBao open-pit mine for practical engineering,using the method of the north, a risk evaluation is made on the stability of slope area.Through the engineering example of calculation shows that,in this paper, the risk evaluation method is reliable and can be used to guide the slope mining design.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
