| 摘 要： | 用强夯处理湿陷性黄土地基的主要目的是消除湿陷性并提高其承载力，目前规范中只有8500kN·m能级以下的有效深度预估值，而15000kN·m的高能级强夯在大厚度湿陷性黄土地区的应用在国内尚属首次．通过工程实例介绍了其试夯情况和深达15m的处理效果，为今后的类似工程提供了参考依据．

| Abstract: | The main purpose of ground treatment with dynamic compaction for collapsible loess is to eliminate collapsible and raise the bearing capacity. But there is only the reinforcement depth of dynamic com- paction under the energy level of 8 500 kN · m in standard. The high energy level dynamic compaction of 15 000kN · m is the first used in big thickness of collapsible loess regions. This paper investigating the situation of test ramming and its reinforcement depth which can get to 15m through an engineering example. also providing reference for the similar projects in the future. |

| Keywords: | high energy level dynamic compaction collapsible loess reinforcement depth. |
