本文阐述了喷锚支护技术的定义及其对基坑边壁加固的原理，土层锚杆和挂网喷射混凝土结构的设计，施工工艺和技术措施。提出了喷锚支护技术与钻孔灌注桩，锚拉桩和槽钢张拉结合的技术措施，解决了大深度、陡坡角、高荷载基坑边壁加固中难题。提出了稳妥而有效的降水措施，为在含水量高的淤泥和淤泥土中进行施工提供了可能性。最后，从技术上，经济上分析了该技术的优越性。
This article expounds the definition of the spray-anchor support technology and the principle of reinforcing the side wall of the foundation pit, the design of the soil anchor bolt and the suspended mesh shotcrete structure, and the construction technology and technical measures. The technical measures of injection-anchor support technology combined with bored piles, anchored piles and channel steel tensioning were put forward, and the difficulties in the reinforcement of large depth, steep slope angles, and high load foundation pit side walls were solved. Safe and effective precipitation measures have been proposed to provide possibilities for construction in silt and silt with high water content. Finally, the superiority of the technology is analyzed technically and economically.
