摘　　要：结合某公路改建工程,提出在加宽路段使用新技术———强夯法施工.为达到提高加宽部分填土路基承载力、减少新老路面不均匀沉降的目的,寻求适宜的施工参数及施工工艺.强夯在该工程的应用,取得了较为满意的经济效果,验证了强夯运用的正确性,为进一步拓宽强夯法的应用范围打下了良好的基础,同时也可为此新技术在公路工程中推广应用拉开序幕.Combining some highway rebuilding project, a new technique, dynamic compaction in widening road construction is put forward. It is expected to raise the bearing capacity and decrease the uneven settlement of the widening road bed; and looking for the feasible construction parameters and construction technique. Application of the dynamic compaction in that project, it obtains the more satisfied economic result, and verifies the accuracy of the dynamic compaction, it is the base for further open widely the application scope of dynamic compaction; at the same time it is the beginning to applying the new technique in highway construction.
