| 摘 要： | 利用静载试验过程的桩顶沉降和桩身轴力实测数据研究大直径扩底桩的荷载传递规律,并利用有限元法对试验过程进行了模拟。结果表明,大直径扩底桩的桩端承担的荷载较大,桩身越长,极限侧阻力越大。

| Abstract: | In order to study the bearing behavior of large diameter belled pile, the load transfer rule was studied with the settlement data and axial load data in the progress of static load test, and the progress of the static load test was simulated by finite element method. The result shows that the load on the pile bottom is higher than the piles in common, and the longer the length is, the threshold friction is larger. |
