Engineering Application of Detections on Backfill Compactness

Abstract:

This thesis introduces the contents of backfill compactness and the detection method. And it also introduces the effects of backfill compactness in engineering: it is an important basis to judge the reliability and stability of backfill foundation. In addition, it takes the maximum dry density detection of on-site backfill and the compacted backfill compactness detection of foundation at Linan contrustion site of Hangzhou Hangyang Heat Exchange Equipment Co., Ltd. for example to specify the engineering application of detections of backfill compactness. At last it puts forward problems existing in the engineering detection on compacted backfill compactness: the variance of the actual maximum dry density and maximum dry density achieved by indoor compaction experiment. And it also provides a corresponding solution called the correction for maximum dry density in sieved gravel soil.
