In this paper , the writer studied a new detecting technique - expanding bolt pullout method by using expanding bolt as bulkhead 本文采用胀栓作为锚固件,研究胀栓拔出法新无损检测技术。
It can be placed without vibration to flow level and degas , more applicable to complex configuration , thin space or where there are densely distributed anchors , better thermal shock resistance than vibration castables with the same material system 施工不需振动即可自流平和脱气,易于施工形状复杂、狭窄和有密集锚固件的部位,抗热震性优于同材质的振动浇注料。
Floors were plate with the main structure ( beam ) link , the length of anchor support should comply with the design requirements and should be less than 50 mm , will be a reliable link anchor pieces , location should meet the design requirements 组合楼板中压型板与主体结构(梁)的连接,其锚固支承长度应符合设计要求且应小于50 ? ,端部锚固件连接应可靠,设置位置应符合设计要求。
To truly reflect complex geometrical layout of bolts , a composite model of three - dimension anchored rock mass has been proposed for numerical simulation . the corresponding formulation of anchored mass ' s combined units has been formed by displacement interpolation theory of fem and statical effective principle . and the corresponding detailed rules has also been advanced 针对加锚岩体的数值模拟,为了真实反映各种锚固件的复杂几何布局,文中给出了三维加锚岩体的组合模型,利用有限元法中的位移插值理论和静力等效原则建立加锚岩体组合单元的相关列式,并提出相应的实施细则。
