摘要
假定拉拔时锚固体与周围岩土体之间的剪切位移荷载传递符合理想弹塑性模型,推导出锚杆抗拔力的解析算式．根据埋设于淤泥质土层中锚杆的拉拔破坏性试验数据,采用该公式计算锚杆抗拔力,并与实测值对比,两者较为吻合．
Based on the assumption that the shear force and the shear displacement between the bolt and the surrounding soil follow a perfect elasto-plastic model, an analytical solution for the anchor pullout resistance is derived. According to the field uplift tests of grouted bolts burried in mucky soil, the pullout resistance of bolt is calculated by the formula and compared with that directly obtained from tests. A good agreement is obtained.
