| 摘 要： | 根据土钉与土体间剪应力-相对位移关系曲线，分析了土钉与土体间荷载传递机理，建立了土钉与土体间应力传递的力学模型。利用截面上的平衡条件，推导了有别于传统假设的作用在土钉上的应力分布及变形表达式，从理论上分析了土钉与土体间的应力传递规律，并结合工程实测数据验证了该模型的合理性。

| Abstract: | Based on shear stress-relative displacement curve between soil nail and soil, the force transferring mechanism is analyzed. A mechanical model of stress transfer is built. The formulas of stress distribution and deformation along the soil nail are given according to equilibrium conditions of the section. The law of stress transferring between soil nail and surrounding soil is analyzed theoretically; the results of the model are agreed with engineering data very well. |
