摘　　要：为研究低能量强夯法和无填料振冲法处理松细砂的适用性和加固效果,进行了一系列试验,结果表明:只要采用正确的施工工艺和参数,两种方法加固此类地基均可取得很好的效果,但它们在地下水位要求、加固深度、工期和造价方面存在一些差异,有各自的使用范围,应根据工程地质情况和加固目标进行选择。In order to research the usability of low-energy dynamic compaction and non-filler vibro-flush for treating loose fine sand and their reinforcing effects, a serial of tests have been carried out. The results indicate that as long as appropriate construction technology and parameters are adopted, both methods can achieve good effect in foundation reinforcement. However, they differ from each other in underground water level requirement, reinforcing depth, construction period and costs, and have their several application scopes which should be selected according to the geological conditions and reinforcement objectives.
