摘要
根据均匀的以及有淤泥夹层的粉质粘土层中扩底斜土锚的原位抗技试验结果，对扩底土锚的抗拔承载机理做了分析，给出了计算这类土锚极限抗拔承载力的方法。
According to the pull--out experiments of several belled tiebacks in a homogeneous silty claystrata and that with a gyttja interacalation, a study on the mechanism of pull-out resistamce of this kind oftieback is engaged. A method of estimating the ultimate pulled-out bearing capacity is also reported.
