砂性土路基的强夯法加固机理及应用

强夯法加固路基是利用夯锤在一定条件下对路基产生的巨大冲击力来处理路基的一种经济高效技术.由于路基土性质千差万别,至今尚未形成一致的看法和系统的理论,主要以经验为基础.结合唐山地区砂性土路基强夯法加固的机理、施工参数的确定和施工工艺分析了对砂性土路基进行强夯加固后的相关检测指标,并论证了该处理技术可行性和施工工艺的适用性.

Dynamic Compaction Method Reinforcement Mechanism and Application of Sandy Soil Subgrade

Dynamic compaction method of reinforcing the subgrade is an economic and efficient technique applying huge rammer impact on embankment under certain condition to do the subgrade treatment. Due to the varies of properties of subgrade, at present it has not formed a consistent view and system theory and is mainly based on the experience. With the mechanism of soil subgrade dynamic compaction method, determination of construction parameters and construction technology of Tangshan, this paper analyzes the relevant test indexes after the sandy soil roadbed consolidation, and demonstrates the feasibility of the processing technology and the applicability of the construction process.
