文章利用落锤式弯沉仪无损、快速等优点,参照路面结构反分析的做法,进行土基模量的线性反演分析。并对落锤式弯沉仪与贝克曼梁的相关性,以及其在挖方路基质量控制、挖方路基换填效果、路基分层施工质量、路床冲击压实效果、台背回填压实效果和路基验收评定中的系统应用进行研究和评价分析,取得较为理想的效果。
In this paper, by using the advantages of drop weight sinker, such as nondestructive and fast, the method of back analysis of pavement structure is used to conduct linear inversion analysis of the modulus of foundation. And the correlation between falling weight deflectometer and Beckmann beam, as well as its quality control in excavation roadbed, embankment replacement effect, subgrade construction quality, roadbed impact compaction effect, backfill compaction effect and Subgrade acceptance assessment of the system application research and evaluation analysis, and achieved more satisfactory results.
