pullout force 中文意思是什麼
pullout force
解釋
拔出力-
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
本文採用ansys有限元程序對脹栓拔出法試驗過程進行彈性理論分析；以修正的摩爾-庫侖破壞準則，在擬合實際破壞面的基礎上推導出極限狀態下脹栓拔出法的混凝土拔出力與混凝土抗壓強度的理論公式，並把該公式與脹栓拔出法測強公式進行了比較。 -
The mechanism of reinforcing steel bar under the press or pull is researched and the characteristics under the pull - press cyclic loading is studied in composite foundation. it shows that the stress concentrating on the reinforcing steel bar and the increasing stress can be seen with the increasing of cyclic times. residual strain always exists after unloading without considering the size of pullout force and increases slowly with the cyclic times
探討了復合地基中抗拔鋼筋的受壓受拉機理及在拉壓循環荷載作用下的性狀，研究發現，隨拉壓循環次數的增加，應力向鋼筋集中，鋼筋承受的壓力隨著增大；無論上拔力大小，卸載后都有殘余變形，並隨著拉拔循環次數的增加而緩緩增加；抗拔碎石樁破壞性狀明顯，可明確的得到抗拔碎石樁的破壞荷載。 -
And then, the four basic models of failure of inserted foundation are expressed, in details this paper focused on three methods of cone of earth solution, liu wenbai ' s, charles ' s of interpretation. aimed at these methods of ignores the base soil normal force, the analysis method of pullout bearing capacity of inserted foundation is amended. finally, the four methods results are compared
然後詳細論述了土重法、劉文白法、 charles法三種計算方法，針對這些方法中都沒有考慮地基土法向反力的不足，對插入式基礎上拔承載力的計算方法提出了一些改進，最後對這些方法的計算結果進行對比。 -
The risk of using the thermally insulated pipeline is that the exterior layers covering the steel pipe may be pulled off if the shear stress on the interface induced by the pullout force from the tensioner is greater than the binding force between two neighboring layers during installation
鋪設單重管最容易出現的問題是由於張緊器張力作用而導致單重管各層之間產生剪切力，如果抗剪能力不足產生相對滑移，就會出現拉脫現象，造成工程事故。
