| 摘 要： | 粉土地基中因周边环境不允许采用挤密桩及振密砂石桩复合地基时，采用钻孔扩底桩具有经济、实用的突出优点，但是它在施工工艺方面还不够完善，尤其是持力层性质及临界厚度等条件不同时，单桩承载力设计参数的选取标准存在较大变化，本文将依据工程实例对上述有关问题进行探讨。

| Abstract: | The compaction pile and sand\|stone vibratory compacting pile composite foundation are not permitted in silty soil in consideration of its surroundings. Yet under\|reamed bored pile has its advantages in terms of economy and utility. Still it has shortcomings in construction techniques, especially when the conditions of critical thickness and the characteristics of the supporting layer are different. Selection standard of design parameter of pile capacity varies largely. Based on engineering examples, this paper discusses the above\|mentioned questions. |
