Bored Piles Construction Safety Comprehensive Evaluation In Permafrost Region

With the deepening of the development of China's Tibet region, Large-scale public infrastructure construction project priority in the development of Tibetan areas, the scale has been increased. Tibetan areas due to the remote, the transportation convenience is poorer, and relatively harsh natural environment, resulting in technology is not developed in the early years was not a larger degree of development, And from the perspective of the development of Tibetan areas in recent years, public infrastructure in Tibet has ushered in the large golden age, In Tibet region large public foundation for outstanding research significance in the construction of bored piles construction is one of them, bored piles because of its features, has more advantages in the Tibetan areas are also expanding the scope of the use.The vast majority of frozen soil in Tibet, and the research on permafrost has been in constant exploration, however, due to global warming, Tibetan areas of permafrost have also been affected. Also is different, the degree of the impact on the construction, and project for permafrost region poses a follow-up questions. Because of the frozen soil properties is relatively unique, the soil after the ice melts decreases the strength of the soil, the influence on reconstruction projects and to complete the project is negative. This makes the study of construction in permafrost area also need some time, within the scope of the project management discipline also need to do some related research construction in permafrost region. Bored piles construction safety comprehensive evaluation this article selects the permafrost area as the research object, through research on influence factors of bored piles construction safety in permafrost region have a comprehensive understanding and awareness.In this paper, through literature analysis, field investigation method, expert consultation method to collect relevant information, and frozen soil conditions as to choose the effect factors of bored piles construction safety, bored piles in permafrost area construction safety comprehensive evaluation index system. In this article research setting, analytic hierarchy process(AHP) combined with fuzzy comprehensive evaluation method as a research method in this paper. After building the traditional construction safety comprehensive evaluation index system of management construction safety comprehensive evaluation index system of Q. Impose the same research on evaluation system of the two methods and the evaluation results of two kinds of mode to compare and analyze. In the process of evaluation, the part qualitative and quantitative evaluation factors into numerical, all data support in this article.Through comparative analysis of the influence of the relationship between factor set, factor set contains the relationship between the factors have a clear instructions. The contrast of two system can find hidden in the hidden relationship between the construction and management, can also analysis the construction, management, the proportion of their impact on the project, The research on permafrost region of bored piles construction, can provide a reference value. According to the comparison and analysis can know that unique management factors of the whole project management mode of construction safety can have the effect of positive influence. Through the study of this article, we can in the actual engineering projects, the project at the same time the traditional mode and management mode of construction safety assessment, reflection is used in the project management behavior is rational and feasible, and generate positive promotion of the project construction safety, it in the actual construction safety for our scheme can provide the reference in the adjustment and improvement, and such reference is basis, to support the data.
