摘要
土钉墙支护技术通过在被加固土体内植入一定长度和密度的细长杆件与喷射混凝土面板,形成了一个类似重力式挡土墙。喷射混凝土与土层面产生嵌固效应;锚杆深固于土体内部,主动支护土体,并与土体共同作用,有效保持和提高围土强度。结果表明:土钉墙支护技术不仅能够达到支护边坡稳定安全,而且具有其他支护方案无法比拟的优点。
Soil-nail wall supporting technology formed a gravity earth-retaining wall by embedding some given size and given density slender bars and sprayed concrete in reinforced soil. Sprayed concrete fixed the soil; anchor arms were embedded deeply in the soil, active supported the soil, and acted with the ,soil, all of these effective kept and increased the strength of the soil. The study showed that soil-nail wall supporting technology not only supported the soil, but it had merits that the other supporting technologies did not have.
