考虑全寿命周期的地下工程开发适宜性评估方法研究

Suitability Evaluation Method of Underground Engineering Development Based on Life Cycle

合理开发利用地下工程是缓解地面交通压力、扩展空间结构、确保工程安全性与耐久性的重要途径,具有良好的发展潜力.从全寿命的角度出发,运用可变模糊集理论,建立了基于全寿命理论的可变模糊集评估方法,并运用工程实例对地面与地下工程对比分析,得出地下工程开发建设的优属度.结果表明:提出的地下工程开发适宜性评估方法能够对拟建地下工程的可行性进行有效评估,方法切实可行,也为类似地下工程的建设提供决策依据与新的评估思路.

The exploitation and utilization of underground space could effectively relieve the pressure of the ground traffic,extend space and ensure the safety and durability of engineering structures,which had good development potential.According to the theory of life cycle and variable fuzzy set,a new variable fuzzy set evaluation method based on life cycle theory was established.By using practical examples to compare the equivalent function of ground and underground engineering,the superiority of underground engineering development and construction was obtained.The results indicated that the proposed method was practicable,and could effectively evaluate the underground engineering,and provided decision-making basis and new assessment ideas for the construction of similar underground projects.
