In order to analyze the bearing mechanism of belled pier with different dimensions, by three-dimensional finite element, a contact model of pier and soil was established.

为了分析不同尺寸条件下扩底墩的承载机理，利用三维有限元，建立墩土接触模型，分析不同墩身长度、扩底直径以及扩大头锅底高度时扩底墩的承载性状。

Based on the load tests of 8 large diameter belled piers and 2 friction piles, the vertical bearing behavior of the belled pier in non-collapsing loess-like soil is studied.

根据同一试验场地厚层非湿陷性黄土状土中8根大直径扩底墩、2根等直径桩的竖向承载力静载试验，对扩底墩的竖向承载性状进行了研究。
