In this paper , the writer studied a new detecting technique - expanding bolt pullout method by using expanding bolt as bulkhead 本文采用脹栓作為錨固件,研究脹栓拔出法新無(wú)損檢測(cè)技術(shù)。
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 施工不需振動(dòng)即可自流平和脫氣,易于施工形狀復(fù)雜、狹窄和有密集錨固件的部位,抗熱震性優(yōu)于同材質(zhì)的振動(dòng)澆注料。
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 組合樓板中壓型板與主體結(jié)構(gòu)(梁)的連接,其錨固支承長(zhǎng)度應(yīng)符合設(shè)計(jì)要求且應(yīng)小于50 ? ,端部錨固件連接應(yīng)可靠,設(shè)置位置應(yīng)符合設(shè)計(jì)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 針對(duì)加錨巖體的數(shù)值模擬,為了真實(shí)反映各種錨固件的復(fù)雜幾何布局,文中給出了三維加錨巖體的組合模型,利用有限元法中的位移插值理論和靜力等效原則建立加錨巖體組合單元的相關(guān)列式,并提出相應(yīng)的實(shí)施細(xì)則。
