Based on the load tests of 8 large diameter belled piers and 2 frictionpiles, the vertical bearing behavior of the belled pier in non-collapsing loess-like soil is studied.
The influence of the pile type and the friction angle of the contact surface on the limit bearing capacity of the piles and the composite foundation is discussed with an example.
通过算例，讨论了桩型及桩土接触面上的摩擦角对散体材料桩及其复合地基极限承载力的影响。

The test of negative skin friction along the single pile is studied, which is modeled after piles of Zhanjiang harbor.
