粉喷桩复合地基在河漫滩相软土地基处理中的应用

Application of Powder Spurt Pile Composite Foundation to Flood-plain Deposit Soft Soil Improvement

结合某市健康园三期工程18#楼软土地基处理工程实例,研究了粉喷桩复合地基处理河漫滩相软土的加固机理和常见检测方法,分析了粉喷桩复合地基设计与施工中常见问题及其解决措施。实际加固效果检测资料表明,18#楼地基经处理后其承载力有了明显的提高,加固效果明显。

Combined with soft soil foundation treatment of the 18th storied building in Health Garden ,this paper studies the reinforce mechanism of improving flood-plain deposit soft soil and frequently used examination methods of powder spurt pile composite foundation. The familiar problems and settlement measure have been discussed in design and construction of powder spurt pile composite foundation. The examination data of field reinforcement effect indicates that bearing capacity of the 18th storied building foundation has been improved and reinforcement effect is obvious.
