【摘要】 注浆作为保障地下工程安全的主要措施和辅助施工工艺,对地下工程及其周边建筑的安全和质量具有非常重要的意义。但注浆效果的检测是行业内共同的难题,为探索注浆效果检测的有效方法,文中在比较现有检测方法的基础上,通过理论分析和实际应用发现地震散射方法能够提供对注浆效果敏感的地震波速分布,以波速为依据能判定注浆效果好坏,确定残留缺陷位置,并且该方法还具有分辨率高、勘探深度大、经济高效、不损坏路面,对交通干扰小的优点,是城市地下工程注浆效果检测的首选方法。更多还原

【Abstract】 As the most frequently used safe measure and auxiliary construction of underground engineering,grouting has much significance in ensuring the safety and quality of underground projects and surrounding buildings.However,it’s hard to detect the effect of grouting.In the interest of seeking a fruitful method to detect grouting effect.In this paper,based on the comparison of existing detection methods,theoretical analysis and practical application,seismic scattering technology is found.This technology provides the seismic velocity distribution,which is the most sensitive to grouting effect.Grouting effect can be evaluated and the location of residual defects can be found by analyzing seismic velocity distribution.This method has high resolution,great exploring depth,good economic utility,and high efficiency.In addition,it doesn’t damage pavement and has little influence on traffic.Because of these advantages,seismic scattering technology is the most suitable method to detect grouting effect.更多还原
