摘要
介绍在京福高速徐州东绕城采空区注浆段应用点面结合的综合检测方法对注浆效果进行检测，通过注浆检测试验表明：（1）注浆达到了预期的效果；（2）各种检测手段中，除钻孔取芯、注水试验等常规直观手段外，孔内三侧向电阻率测井和高密度电法对饱水采窄区注浆效果检测是非常有效的方法：（3）只有采用点面结合的综合检测方法才能对注浆效果进行全面准确的评价。
The point-surface comprehensive measurement method to check the grouting effect in mined-up region under highway is presented. Through comprehensive measurement test, it indicates that the prospective grouting effects are verified. Besides the general and direct methods such as bole sampling and injection test, etc., three-lateral resistivity logging and high-density resistivity methods are effective to check the grouting effect in saturated mined-out region. Even if the point-surface comprehensive measurement methods are adopted, the grouting effect can be evaluated accurately and fully.
