| 摘 要： | 针对岩溶路基注浆质量检测的难度,基于现场典型地质断面,建立室内裂隙灰岩模型,进行注浆前后多测试断面的电测深检测试验数据解释分析,并对比模型中实际浆液扩散情况。试验结果表明:水泥浆液注入后,模型视电阻率较注浆前明显降低,当注浆后视电阻率降低幅度大于等于15%时,注浆效果较好。模型注浆后的合理检测时间为注浆完7天后。现场检测试验基本能够验证模型试验结论,但现场检测试验受地下水位的影响较大,会造成局部评判失真。

| Abstract: | Due to the difficulty of quality test of karst roadbed,based on typical field geological sections,a model of stenopeic limestone is established,and analysis of the results of resistivity sounding test on many sections before and after grouting is carried out,and comparison with the real diffusion area in the model is also performed.The results suggest that after the cement flow is injected into the model,the apparent resistivity decrease more obviously than before grouting.When the decreased extent is equal... |
