| 摘 要： | 本文根据某高速公路软基处理中不同桩长的水泥土搅拌桩单桩载荷试验结果,探讨了复合地基中水泥土搅拌桩的有效桩长。研究结果表明:水泥土搅拌桩的有效桩长与地基条件和桩身强度直接相关,在设计中考虑有效桩长有其必要性。最后,作者对有效桩长的确定方法提出了建议。

| Abstract: | Based on the load tests carried out in soft soil foundation treatment project of an expressway under construction, the effective cement-soil mixing pile length in composite foundation was explored. Results obtained from this research indicate that the effective length of cement-soil mixing pile is dirrectly related with the pile shaft strength and the foundation soil conditions, and it is necessary to consider the effective pile length in the foundation improvement design. At the end, authors suggest a method to determine the effective pile length. |
