摘要
准确检测土层含水量、采取注浆加固措施能够有效预防基坑渗水问题。通常土层的含水量、注浆加固质量检测采用钻孔和观察井等方法。基于无损检测的理念,结合工程实例介绍地质雷达探测法。该方法主要通过分析雷达图的振幅、波速和波形特征,能够科学地判断出土层的含水量及注浆加固质量情况。
To accurately test the moisture content of soil layers and grouting reinforcement can prevent the water seepage effectively. Drilling holes on the ground and observation well are usually used to detect the soil moisture content and grouting quality. Based on the conception of non-destructive testing（ NDT） and real engineering cases,this paper introduces the ground penetrating radar method. The technique mainly analyzes the amplitude of radar map, features including wave velocity and wave shape, thus can scientifically estimate the moisture content of soil layers as well as the grouting reinforcement quality.
