强夯是一种有效的地基加固新技术,国外已普遍使用。鉴于其机理复杂,理论研究尚不成熟,国内资料不系统,使用尚不普遍。因此,如何迅速地测定和准确评价强夯效果,进而推动其应用和发展,尚属目前急待解决的问题。本文通过一个工程实例,介绍了强夯施工与现场测试;阐明了静力触探的适宜性;根据实测资料,分析了强夯法加固素填土地基所取得的技术效果。
Dynamic compaction is an effective foundation reinforcement technology, which is widely used abroad. In view of its complex mechanism, the theoretical research is not yet mature, the domestic information is not systematic, and its use is not yet widespread. Therefore, how to quickly measure and accurately evaluate the effect of dynamic compaction to promote its application and development is still an urgent issue to be solved. In this paper, through a project example, the dynamic compaction construction and on-site testing are introduced. The suitability of static penetration testing is expounded. According to the measured data, the technical effect of dynamic compaction method on the fill foundation is analyzed.
