挂网喷锚支护技术是提升边坡稳定性较为常见的支护措施之一,尤其是在边坡低岩性强度或高岩石风化度情况下尤为适用。其主要利用了岩体的粘性、弹性与塑性等物理属性的特点同时结合在岩体中开挖洞室后会引起岩体变形的时间效应进行支护与加固操作。笔者从江西省永新县洞口水库实际情况出发,通过挂网喷锚支护技术的应用对大坝前坝坡进行了支护与防护。
One of the most common support measures for slope stability improvement is hanging net spray anchor support technology, especially in the case of low rock strength or high rock weathering degree. Its main use of the physical properties of rock mass such as viscosity, elasticity and plastic characteristics at the same time combined with rock excavation caverns will cause deformation of the rock time effect of support and reinforcement operations. Based on the actual situation of Dongkou Reservoir in Yongxin County, Jiangxi Province, the author carried out the support and protection of the dam slope in front of the dam through the application of the technology of spray-anchor spraying.
