THE EFFECT OF CRD METHOD OF CIVIL AIR DEFENSE TUNNEL ON THE SURFACE

Institute of Civil Engineering and Transportation, Liaoning Technology University, Fuxin 123000, China

摘要

摘要: 在监测数据的基础上，运用Matlab等软件，结合矿业开采沉陷理论，针对隧道双侧扩挖对地表的影响进行了初步研究，得到了隧道双侧扩挖对地表的影响范围。提出了沉降曲线拐点的概念及其特征，区分了沉降变化的低速区和高速区，为今后既有隧道扩挖的施工和监测设计提供了依据。

Abstract: This paper made a preliminary study on the effect of CRD method of civil air defense tunnel on the surface based on the monitoring data, the Matlab software and the mining subsidence theory. The impacted zone was confirmed. The settlement curve's inflection point and its characteristics were found. The lower velocity zone and higher velocity zone of settlement variation were distinguished. These achievements could be referenced for the design of relevant construction and monitoring of the old tunnels.
