在分析惠州地区桥头跳车产生原因的基础上,提出了台背回填采用“刚柔过渡”的设计方案。为实现设计,提出了台背回填长度的确定方法,对该地区典型台背填料的技术性能进行了研究。 Based on the analysis of the causes of the jumping at the bridgehead in Huizhou area, a design scheme of “rigid and flexible transition” was proposed. In order to realize the design, a method to determine the length of backfill was proposed, and the technical performance of typical backfill in this area was studied.
