| 中文摘要: |
| 本文介绍了用大粒径碎石桩加固不排水强度低于20 kPa的超软弱河道边坡的施工方法，碎石桩单桩和复合地基的检测内容和检测方法。提供了由测试数据获得的抗剪强度指标与面积置换率的关系、充盈系数与密实电流和留振时间的关系。用实测碎石桩复合地基抗剪强度计算了施工期边坡稳定安全系数，其结果满足规范要求。工程实例表明大粒径碎石桩加固人工河堤淤泥土层是成功的。 |
| 英文摘要: |
| The construction and quality inspection method for large size gravel columns reinforcing the very soft river slope are introduced.The relation between shear strength and area replacement ratio,relation between over charged coefficient and load current,as well as the load time are obtained from field experiments.The safety factor of a canal slope under construction is calculated by using the shear strength obtained from experiments and is in accord with the need of code. |
