为了获得方便快捷、经济、可靠的浆液实际注入率测量方法,为注浆量验收及注浆质量检测提供重要参数,文章采用了断面法的基本思想,引入数字图像处理技术,对断面图像信息进行处理. 首先介绍了数字图像处理技术的基本原理和步骤, 并结合理论情况下劈裂注浆的浆脉扩散形式, 分析了以数码照片来等效注浆断面的可行性.然后通过现场单孔注浆试验,分析了以数字图像处理技术来测量注入率的可靠性.结果表明:以数字图像处理技术来选取浆脉所占像素比,结果变异性小,可重复性好;以图像处理技术为基础测算的注浆量与实际跟踪记录的注浆量具有很好的一致性,在本现场试验条件下的实际注浆量约为测算量的1.1~1.2倍. 最后利用Photoshop在选取目标区域上的优势和MATLAB编程批处理的优势对处理方法进行了推广,使处理结果更为有效,更适合工程应用.

To find a convenient, economic and reliable method to measure actual grout injection rate and provide important parameters for grouting volume acceptance and quality inspection, this paper uses the digital image pro-cessing (DIP) technique to obtain information for the cross section diagram based on the section method. First it introduces basic principles and steps of this technique and discusses the feasibility of digital images for equiva-lently substituting the actual grouting section under the type of theoretical fracture grouting diffusion, then it ana-lyzes the reliability of this technique through an onsite single-hole grouting test. The results show that the grout injection rate judged by the DIP technique has little variability and good repeatability, and the grouting volume calculated based on the DIP technique is about 1.1~1.2 times the measured one, showing a sound agreement be-tween them. Lastly, in light of the advantages of Photoshop in selecting the target area and MATLAB in batch programming, this method is generalized to be more effective and suitable for engineering applications.
