内蒙古准兴重载高速风积砂高填方路基施工技术研究

THE RESEARCH OF CONSTRUCTION TECHNOLOGY OF EOLIAN SAND IN HIGHFILL SUBGRADE OF INNER MONGOLIA ZHUN- XING HEAVY LOAD

本文针对内蒙古准兴重载高速公路A0合同段风积砂高填方路基实际施工中遇到的问题,通过现场试验,确定出风积砂现场施工最佳松铺厚度为40cm^50cm之间;同时也对强弱振压实进行比较,强振对15cm以下的部分压实效果较为明显,但对表面15cm破坏也更为明显,弱振对15cm以下深度压实效果不明显,但是对上层的破坏较小。因此,在强弱振压选择上应结合现场填料含水量及其它条件合理采用。

This thesis mainly studies the compaction effect of the eolian sand in practical engineering construction, the best thickness of weak vibration compaction, the advantages and disadvantages of a series of site construction technology, finally through repeated tests, the Aeolian sand site best loose paving thickness is between 40cm - 50cm, part of the compaction effect and strong vibration on the 15cm is obviously, but on the surface of 15cm damage is more obvious, weak vibration below 15cm depth of compaction effect is not obvious, but the damage is small, static pressure on the 15cm compaction had no effect.
