摘要
阐述了腐蚀弱化地基产生的根源,说明了地质雷达在注浆加固工程中应用的基本原理和方法特点,结合实际注浆加固工程进行了注浆前后的检测对比。钻探和地表沉降观测结果表明:地质雷达法对介质电性特征变化有良好的敏感性,可用于注浆工程的方案设计、效果检测,实现注浆工程的全程监控。
The causes of the corrosive weakened foundation are discussed.An example from Groud Penetrating Radar(GPR) before and after grouting enforcement is given to illuminate the effect of the method.The results of drilling and settlement obserration show that GPR is sensitive to the change of dielectric properties.It can be used in project design and grouting engineering detecting in monitoring the whole process.
