摘要
从施工和裂缝方面分析了高速公路路基拓宽新老路搭接存在的问题,探讨了土质路基、填石路基及土石混填路基的施工技术要点,总结了影响路基压实的因素,为今后新老路基的搭接提供了参考借鉴。
The paper analyzes new-old road connection problems in highway subgrade widening from two aspects of construction and cracks,explores construction technology points of soil subgrade,rock-filling subgrade and earth-rock-filling subgrade,and summarizes factors influencing subgrade compaction,which has provided some guidance for new-old subgrade connection.
