| 摘 要： | 水泥土搅拌法处理软弱地基的设计与施工技术日益成熟，但作为处理效果评价依据的测试方法尚不完善．通过对现有手段进行综合比较，轻型动力触探简便、快速、经济，是检测水泥土搅拌法处理效果的有效方法；并给出了估算复合地基承载力的公式．工程实例验证表明，采用轻型动力触探来估算加固后复合地基的承载力，与静载荷试验所得的承载力较为接近． |
| 关 键 词： | 水泥土搅拌桩 复合地基 轻型动力触探 |

| Abstract: | The design and construction technique of the cement soil mixing method used in weak foundation is well developed,but testing method for the basis of evaluation treatment is not perfect.From a comprehensive analysis of all methods used now, the light dynamic penetration test is proved to be simple, fast, and economic while effective in detecting the improvement result of the cement soil mixing method. A formula that estimates the loading capacity of composite foundation is put forward.Verified with the solid example of engineering, the loading capacity of composite foundation estimated by the light dynamic penetration is close to that by the static test. |
| Keywords: | cement soil mixing pile composite foundation light dynamic penetratton test |
