| 摘 要： | 针对锚索预应力作用于岩体内形成的应力场状况,利用弹性力学中的Boussinesg解和R.D.Mindlin解,研究处于锚头的岩石是否会由于挤压而产生破坏,锚根附近的岩石是否会由于张拉而发生破坏。通过研究,得出了锚索预应力作用于岩体内各受力部位形成的应力特点;以及为避免群锚效应,锚索应保持的合理间距。将此研究应用于江苏省连云港将军崖岩画的加固工程中,取得了理想的工程效果。

| Abstract: | The stress field formed by anchoring in rock and soil with prestressed anchor cable can be simulated with the Boussinesg solution and the R.D.Mindlin solution in elastic mechanics.Based on that analysis,it is studied whether the rock at the anchor ending is destroyed or not,the right space should be keep between anchors in order to avoid the effect of the cable group.The results are used to strengthen rock mass where rock drawing exists in Jiangjunya mountain in Lianyungang city and the anticipated results has been obtained. |
