The coupling system has a fiber insert - pullout structure, avoiding the trouble of adjusting the fiber each time
耦合系統為光纖插拔式結構，避兔了透鏡耦合時每一次調整的麻煩。 -
The friction coefficient, critical vertical loads and critical frictional resistance strength have been worked out by means of the pullout tests under the different vertical loads, analysis of frictional characteristics between soil and material and analysis of the different work mechanism between direct shear test and pullout tests. the creep characteristic parameters of some typical reinforcement materials have been obtained by the creep tests under the loads for a long time and the rheological analysis
對幾種典型筋材在不同法向荷載下進行了拉拔試驗，並進行了筋材與土介質的界面摩擦特性分析，直剪試驗與拉拔試驗不同機理分析，找出了影響摩擦特性試驗結果的主要因素；得出了筋材在工作荷載階段的摩擦系數、臨界法向中南大學博士學位論文荷載和臨界摩阻強度。 -
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參數；對試驗數據進行系統的回歸分析，得出脹栓拔出法的測強公式及與回彈法、超聲法綜合測強公式，並對這幾個測強公式進行了精確性比較，發現脹栓拔出法的混凝土拔出力與混凝土抗壓強度具有良好的相關關系。
