结合具体工程,对强夯法在高填方堆场轨道基础地基处理中的适应性和可行性进行了系统阐述,并对强夯参数进行了全面的设计、试验与效果检验。认为对于土石混合料回填的高填方地基上的轨道基础,采用强夯法处理是合适的。通过对强夯地基的检测结果表明,强夯法处理该类回填地基的效果较好,强夯处理后,地基承载力提高明显、压缩性减小。
Based on the concrete project, the adaptability and feasibility of dynamic compaction method in the foundation treatment of high-fill yard track foundation are systematically described, and the design, test and effect test of dynamic compaction parameters are comprehensively carried out. It is considered that it is appropriate to adopt dynamic compaction method for the rail foundation on the high-fill ground for the backfilling of soil-stone mixture. The test results of dynamic compaction foundations show that the effect of dynamic compaction on such backfilled foundations is good. After dynamic compaction, the bearing capacity of foundation is obviously increased and the compressibility is reduced.
