摘　　要：通过淮安三线船闸闸室墙结构中土层锚杆极限承载力的现场试验研究,依据作用荷载下的位移变化图形,分析土层锚杆的变形规律,提出了以锚固体刚性位移为控制条件或以锚固段周围土体整体稳定为控制条件确定的土层锚杆极限承载力。The paper analyses the distortion law of soil layer anchor rod by field test of the limiting bearing capacity of soil layer anchor in Huai-an 3rd lock chamber structure,according to the displacement variety sketch under loading.Then,it gives the controlling conditions with the stress of free anchor,or with the integral stability of soil surrounding the anchorage zone to determine the limiting bearing capacity of the soil layer anchor.

关 键 词：土层锚杆 极限承载力 现场试验 位移图形分析
