大坪岩堆的固结灌浆综合评价采用钻探等野外地质调查、检测、采样分析工作,通过现场野外实测法及XRD法分析对比确定岩堆灌浆率,结果表明,两种灌浆率的计算结果误差为3.3%,定量评价灌浆固结效果再结合物探验证,其结果较为准确,可为类似工程提供参考。
The comprehensive evaluation of consolidation grouting in Daping rock mass is based on the field geological survey, testing and sampling analysis of drilling and other field work. The field grouting and XRD analysis are compared to determine the filling rate of the rock mass. The results show that the error of the two grouting rates is 3.3%, quantitative evaluation of the effect of grouting and consolidation geophysical exploration proved that the results are more accurate and can provide reference for similar projects.
