摘要
为应对盾构隧道渣土日益庞大的产量,形成对盾构渣土的资源化利用体系的系统性认识是有必要的.取样得到国内6个不同城市的典型盾构隧道工程所产生的渣土,并对其进行试验得到了不同城市盾构渣土的含水率、液塑限含水率、颗粒粒径、贯入指数、CBR承载比等物理力学性质,探讨了盾构渣土潜在的资源化利用前景.阐述了目前盾构渣土的资源化处理技术的原理、适用场景、品质要求,据此结合盾构渣土的物理力学性质进行分析,提出了不同性质渣土的分类体系,从而说明不同性质渣土可能的处理方式,进一步总结出一套盾构渣土综合利用途径流程,以期为我国的盾构渣土的资源化利用发展提供一定参考.
In order to cope with the increasing output of shield tunnel muck,forming a systematic understanding of the resource utilization system of shield tunnel muck is needed.In this paper,the authors obtained the muck produced by typical shield tunnel projects from six different cities in China,and the basic properties of the shield tunnel soil,such as water content,liquid-plastic limit water content,particle size,penetration index and CBR,are obtained through the tests.The potential resource utilization prospect of shield tunnel muck is discussed.This paper also introduces the principles,applicable scenarios and quality requirements of the current resource treatment technology of shield tunnel muck.Based on the analysis of the physical and mechanical properties of muck,it puts forward the classification system of different properties of muck,thus explaining the possible treatment methods of different properties of muck,and further summarizes a set of comprehensive utilization approaches and processes of muck.It is expected to provide some reference for the development of the resource utilization of shield tunnel muck in China.
