| 摘 要： | 在强夯法处理湿陷性黄土路基施工中,为了及时掌握和了解强夯加固深度,并对加固效果进行正确评估,利用测振仪进行现场测振,通过对测得的振动波参数进行数值分析,获得强夯法有效加固深度计算公式,同时利用重力触探方法对强夯后路基承载力进行平行检验.结果表明,有效加固深度计算公式与经验公式有较好的一致性,采用测振仪测控强夯法处理湿陷性黄土路基加固效果是一种有效的新方法.

| Abstract: | It is important to control the effective strengthening depth in the dynamic consolidation of collapse loess roadbed. The consolidation effect was evaluated by analyzing the data of vibration wave from the field test and deducing the formula of strengthening depth. The parallel test of the roadbed strength after consolidation was done by gravity reconnaissance. The better consistency of the derived formula of strengthening depth with the empirical formula proves it is a new and effective method to control the consolidation effect by vibration measurement. |
