摘要
为保证沙漠地区陡立边坡面在施工扰动、喷射混凝土的冲击力作用下不发生局部破坏与滑塌,能够施工形成满足设计要求强度的喷射混凝土面层。在综合考虑沙漠地区超密砂层的强度和稳定性特点以及施工工艺各环节影响的基础上,通过在北非沙漠地区现场陡立边坡挂网喷射混凝土施工试验研究与实践,成功解决了沙漠地区陡立边坡喷射混凝土施工难题,取得了良好的社会效益和经济效益。
In order to ensure that the steep slope surface in desert area does not suffer local damage and collapse under the action of construction disturbance and shotcrete impact force, it is possible to construct a shotcrete surface layer that meets the design requirements. Based on the comprehensive consideration of the strength and stability characteristics of the ultra-dense sand layer in the desert area and the influence in each link of the construction process and through the experimental research and practice of the construction of hanging net shotcrete on the steep slope in the desert area of North Africa, the construction problem of shotcrete on the steep slope in the desert area has been successfully solved and good social and economic benefits have been achieved.
