摘要
Abstract
Kunming new airport is located on the karst area with 234 development karst funnels, the density of karst funnel is up to 11.9 / km2. If the foundation theatment is improper, it would be leading to the issues of post-settlement and foundation stability. Representative experiment area was selectd to study different treatments. The data of in-situ velocity test, standard penetration test, loading test are compared between the ones obtained before and after treatment. The results show that the treatment effects are good by the compaction replacement method with 3500 kN·m and 4500 kNm. But the effect of 2500 kNm is slightly poorer.关键词
