摘要
采用现场大型模拟试验平台进行原位模拟灌浆试验,利用试验得到的数据结果,运用多元回归分析法,得出了浆液扩散半径与灌浆压力、浆液水灰比之间的关系.模拟灌浆试验结果应用表明:统计分析所得公式计算结果与实际灌浆工程开挖检查测得的浆液扩散半径非常接近,说明此公式对于实际灌浆工程具有一定的指导作用.
The field simulation grouting experiment is carried out at the in-situ large-scale simulation experiment platform. According to experimental data results, the relationship between grout diffusion radius and grouting pressure, grouting time and ratio of water-to-cement is obtained by using the multiple-unit regression analysis method. Application results of simulation grouting experiment shows that calculation result of the formula obtained by statistical analysis is very close to grout diffusion radius measured by the actual grouting project, so as to provide a certain guidance for actual grouting projects.
