摘要
文章对常吉高速9A合同段K93＋520～720段采空区进行补充物探，提出相应的工程处治方案，并进行方案优化比选，最终采用开挖回填、强夯等综合的处治方案，取得良好效果。
This article takes the goal supplementary geophysical methods in the Chang-ji high-speed of 9A contracts of section K93＋520＋720, and puts forward corresponding engineering treatment programs,and furthermore optimizes the comparison and selection, finally summarize that excavation backfilling, tamping and so on integrated treatment programs can make good effect.
