摘要
在对现有土钉设计计算方法进行分析的基础上,指出了其所存在的不足,进而提出一种基于极限平衡分析的土钉内力计算方法.为检验该方法的可靠性,在一实际工程中进行了土钉内力的测试.测试结果表明,土钉受力仅为目前计算方法的1/8,显著小于按现有方法的计算结果,此方法与实测结果最为接近.
On the basis of analyzing the current design and calculation methods of soil nail, the authors point out their deficiency and put forward a new method based on limiting equilibrium. To check the reliability of this method, an in-situs test of the interior force of soil nail in a practice engineering was made. The measured results show that the actual force of the nail is only a eighth of the result from the current calculation method. But the proposed method by the authors can produce very close result to the in-situs measured ones.
