摘要
随着城市化进程的加快,地铁工程在全球范围内得到了快速发展.然而,地铁建设过程中产生的桩基泥浆、盾构土处理一直是一个环境和工程的难点、重点.桩基泥浆、盾构土的资源化利用,不仅能够有效解决这一问题,还能促进低碳岩土工程的发展,实现可持续发展的目标.介绍了我国地铁工程现状,盾构施工所产生的盾构泥渣方量,分析了盾构泥渣的工程性质及其处置方法现状.总结了国外先进处置建筑垃圾的法律体系,对比分析我国现有法律法规及政策上的不足.讨论了盾构泥渣的产生、管理以及处置过程中的碳排量计算理论.并以无锡地铁建设运行为例,研究了以盾构泥渣改良为“可控性能流态固化土”回填无锡地铁6号线三阳地铁站地下防空洞和东风站清障、回填项目案例,以期为地铁工程盾构泥渣的利用提供参考.
With the acceleration of urbanization,subway projects have rapidly developed worldwide.However,the disposal of pile foundation slurry and shield soil generated during subway construction has long posed significant environmental and engineering challenges.The resource utilization of pile foundation mud and shield soil can effectively address this issue,promote low-carbon geotechnical engineering,and achieve sustainable development goals.This paper introduces the current status of subway projects in China and the volume of shield mud produced during construction.It also analyzes the engineering characteristics of shield mud and its disposal methods.It summarizes advanced legal frameworks for construction waste disposal in foreign countries,comparing and analyzing the shortcomings of existing laws,regulations,and policies in China.This paper introduces the theory of carbon emission calculations during the generation,management,and disposal of shield structure sludge.Using the construction and operation of the Wuxi subway as a case study,this research examines the backfilling of underground air-raid shelters at Sanyang and Dongfeng stations of Wuxi subway Line 6 with shield structure slag transformed into controllable performance fluidized solidified soil,providing a reference for utilizing shield structure slag in subway projects.
