摘要
注浆效果的检测与评价是保证既有房屋地基注浆质量达到设计要求的重要环节,研究既有房屋地基注浆效果的检测与评价方法具有重要的工程意义.依托某大学宿舍楼地基处理工程,采用地质雷达法、重型动力触探试验及钻孔取芯法对既有房屋地基的注浆效果进行评价,三种检测方法得到的评价结果相互验证、补充,为类似注浆加固工程的检测与评价提供借鉴与参考.
The detection and evaluation of grouting effect are important links to ensure that the grouting quality of the existing building foundation meets the design requirements.It is of great engineering significance to study the detection and evaluation methods of the grouting effect of the existing building foundation.Relying on the foun-dation treatment project of a university dormitory building,the grouting effect of the existing building foundation is evaluated by using the geological radar method,heavy dynamic penetration test and borehole coring method.The evaluation results obtained by the three detection methods are mutually verified and supplemented,which can provide reference for the detection and evaluation of similar grouting reinforcement projects.
