| 摘 要： | 在软岩隧道支护中,大多数情况下需要向上钻孔打锚杆,目前应用较多的中空注浆锚杆和砂浆锚杆在向上打锚杆的情况下,均存在注浆不饱满及不能形成快速初锚力的问题,影响支护效果和工程安全。自旋注浆锚管能比较好的解决上述工程中存在的技术缺陷。在软岩隧道支护中,自旋注浆锚管的抗拔力是至关重要的技术参数,关系到锚固体系的安全。本文根据自旋注浆锚管的结构特点和作用机理,对其抗拔力的计算理论进行了探讨,对实际支护工程有一定的参考作用。

| Abstract: | In the support project of soft-rock tunnel,it needs to install roof bolting in most cases.However,the hollow pouring anchorage rod and mortar bolt that are used widely in the current application exist the problems of unfilled grouting and none rapid initial anchoring force that affect the support effect and engineering safety.The Self-screwed Slip Casting Tube Bolt can solve the existed technical problems well in the project.In the support project of soft-rock tunnel,the pullout resistance of the Self-screw... |
