填方工程压实指标检测技术的综述

The review of detection technology of compaction index filling project

填方工程是道路、桥梁、水利等工程的基础,而填土的压实指标是保证质量的关键,近年来各种工程对于填方工程质量的要求也更加严格。目前压实指标的检测有很多种方法,传统的检测方法大多都费时费力,而且有些方法的操作十分复杂容易精度不够,远远满足不了快速无损检测的要求。本文从检测方法的原理、适用范围、优缺点等方面将国内外常用压实指标检测技术加以分析与比较,对填方工程压实指标检测的研究与发展具有重要意义。

Filling project is the foundation of embankment, bridge, hydraulic engineering and other projects. Compaction index is the key to ensure the quality of filling engineering. In recent years, the quality requirements of all kinds of embankment engineerings are also more stringent. At present, there are many methods to detect compaction indexes, most of the traditional detection methods are time- consuming and laborious, complex, the precision is not enough and far from being able to meet the requirements of rapid non-destructive testing. This paper compared and analyze the commonly used compaction index detection technology from the principle, scope of application, advantages and disadvantages. This research has important significance for the research and development of test embankment compaction index.
