碎石土回填地基工程地质条件较为复杂,若采用动力触探进行大面积检测,时间长、工作量大、成本高,并且容易漏测地基薄弱部位。本次采用多道瞬态面波法进行地基检测,通过面波波速剖面图分析碎石土回填地基软弱体位置及大小,为地基处理设计提供参考。分析结果表明:对于碎石土回填地基,动力触探检测手段存在局限性,综合采用面波法、动力触探试验等手段才能获得准确、可靠的检测结论。
Gravel soil backfill foundation engineering geological conditions is more complex, if the dynamic detection of large area detection, a long time, heavy workload, high cost, and easy to miss the weak foundation of the site. This time using multi-channel transient surface wave method for foundation testing, surface velocity profile by gravel soil backfill analysis of soft soil location and size, provide a reference for the design of foundation treatment. The analysis results show that there are some limitations to the dynamic detection method for the gravel soil backfill foundation. Comprehensive and reliable methods such as surface wave method and dynamic penetration test can be used to obtain accurate and reliable detection results.
