介绍了强夯法加固机理,结合工程实例,选择代表性区域进行试夯,通过试夯区现场试验监测对不同填料地基土单点夯击沉降量与夯坑周围地表变形进行了对比分析。 The reinforcement mechanism of dynamic compaction method is introduced. Based on the engineering examples, a representative area is selected for trial ramming. By means of on-site test and monitoring in the test-ramming area, the single-point compaction settlement of ground with different filler soil is compared with the deformation of ground surface around ramming pit.
