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)。
Finally , the thesis analyzed the concrete failure mechanism of expanding bolt pullout method and summarized the influence of it 本文分析了脹栓拔出法混凝土破壞機(jī)理,總結(jié)了脹栓拔出法的各種影響因素。
Thirdly writer , using linear elastic theory and finite element program ( ansys ) , analyzed expanding bolt pullout test . fifthly , writer using the modified mohr - coulomb failure theory , on the base of curving failure surface , derived a theoretical formula between pullout force and compressive strength . then the thesis compared the formula with the strength - detecting formula of expanding bolt pullout method 本文采用ansys有限元程序?qū)γ浰ò纬龇ㄔ囼?yàn)過(guò)程進(jìn)行彈性理論分析;以修正的摩爾-庫(kù)侖破壞準(zhǔn)則,在擬合實(shí)際破壞面的基礎(chǔ)上推導(dǎo)出極限狀態(tài)下脹栓拔出法的混凝土拔出力與混凝土抗壓強(qiáng)度的理論公式,并把該公式與脹栓拔出法測(cè)強(qiáng)公式進(jìn)行了比較。
Firstly , in the thesis writer studied and gained each test parameter of expanding bolt pullout method , and by using test data , writer regressed and gained the strength - detecting formula of expanding bolt pullout method . at the same time , the compositive strength - detecting formulas of expanding bolt pullout method , rebound method , ultrasonic method were gained . secondly , writer compared expanding bolt pullout method with them 本文研究確定了脹栓拔出法的各種試驗(yàn)參數(shù);對(duì)試驗(yàn)數(shù)據(jù)進(jìn)行系統(tǒng)的回歸分析,得出脹栓拔出法的測(cè)強(qiáng)公式及與回彈法、超聲法綜合測(cè)強(qiáng)公式,并對(duì)這幾個(gè)測(cè)強(qiáng)公式進(jìn)行了精確性比較,發(fā)現(xiàn)脹栓拔出法的混凝土拔出力與混凝土抗壓強(qiáng)度具有良好的相關(guān)關(guān)系。
