基于三角模糊数-TOPSIS的既有高铁近接地基加固方案优选
|
摘要
邻近既有高铁新建线的地基加固会严重影响既有高铁运营安全,地基加固方案优选是近接工程研究的焦点问题之一,但目前针对近接工程地基方案优选研究较少。结合既有高铁近接工程特点,在综合考虑影响地基加固方案选择因素基础上,建立地基加固方案优选指标;提出基于三角模糊数-TOPSIS优选模型,并将其应用于新建曲阜至临沂线近接京沪高铁地基加固方案优选进行分析验证。研究结果表明:该模型对于近接既有高铁地基加固方案优选具有一定可靠性与实用性,不仅为近接地基加固方案优选提供了一种新方法,同时为建立近接工程类似项目的综合评价指标和优选方案奠定了理论基础。
The optimization of the foundation reinforcement scheme is one of the key problems in the study of the approaching project because the foundation reinforcement of the new lines approaching the existing high speed railway may seriously affect the safety of the existing high speed railway. However,few current studies address this issue. This paper establishes the evaluation indexes of schemes for the foundation reinforcement approaching the existing high speed railway based on the characteristics of approaching projects and comprehensive consideration of the factors affecting the selection of foundation reinforcement schemes. A scheme optimization model based on the triangular fuzzy number-TOPSIS is proposed and applied to analyzing the new railway line from Qufu-Linyi adjacent to Beijing-Shanghai high speed railway and verifying the optimization of the foundation reinforcement scheme. The results show that this model is reliable and practical for the optimization of foundation reinforcement approaching the existing high speed railway. This not only provides a new method for optimizing evaluation of foundation reinforcement scheme,but also lays a theoretical foundation for the comprehensive evaluation index system and optimization plan of similar projects.
