摘要:
将注浆层空间中地质雷达信号差和面波反演后波速差作为评判因素，对注浆密实度进行综合评判.经推导得出两评判因素与注浆密实度为近似线性关系；采用典型试验数据，用主成分法计算出两因素的权重集为{07218，02782}；根据注浆密实度情况，将评判集分为4个等级，即{密实，较密实，较差，极差}.共进行了两次大规模模型试验，分别用于建立检测模型和结果验证，浆液凝固后可以移走上部平台，对表面凹坑精确测量，保证了数据的可信度.经检验，直径超过20 cm凹坑的判断准确率为100%，10～20 cm为81.8%，5～10 cm为60%，小于5 cm为304%.
Abstract:
The difference of ground penetrating radar signal intensity and the speed difference of surface wave inverted were appointed as fuzzy evaluation factors to evaluate the grouting intensity comprehensively. According to deduction, the relation of the two elements and grouting intensity was approximate linear. With typical experiment data, the weighting set was calculated as{0721 8，0278 2} by principle component analysis method. According to grouting intensity, the evaluation set was divided into 4 grades, which are {compact, relatively compact, relatively poor, extremely poor}. Two large scale model tests were proceeded to create evaluation model and to validate results respectively, and the hole depth on the platform surface was measured accurately later, so the data is reliable. Upon examination, the judging accuracy to the hole whose diameter exceeds 20 cm is 100%, 81.8% to 10\|20 cm, 60% to 5\|10 cm, and 304 to 0\|5 cm.
