Introducing magnetic memory effect and detection theory summarily, using the data measured by TSC-1M-4 to analysis the basic feature of the areaofstressconcentration.
简要介绍了磁记忆效应和检测原理,并用TSC - 1 M - 4测得的数据分析了应力集中区的基本特征。

Because the natural stress field is changed due to tunneling roadway, a stressconcentrationarea appears in rock of surrounding roadway that cause roadway deformation or destruction.
由于巷道掘进破坏了原岩地应力场,使围岩应力重新分布,应力集中区的高应力造成巷道变形破坏。
