高速公路下伏采空区治理工程质量检测方法研究

A Study on Quality Inspection Methodology of Goaf Harnessing Engineering under Expressway

高速公路下伏采空区治理工程的质量对高速公路建设至关重要。在焦晋高速公路采空区注浆治理工程中,为准确评价其治理质量和治理效果,应用钻探、岩土测试、综合物探和变形监测等方法对治理工程进行了专题研究,在实践的基础上,阐释了各种检测方法的有效性。在综合物探检测方法中,首次提出了高分辨率地震利用反射波品质因数评价注浆效果的新思路,并推荐了各种检测方法评价采空区治理效果的评价指标和针对不同工程特点的检测方法优化组合模式。

The quality of goaf harnessing engineering under expressway is extremely important to the construction of expressways. In goaf grouting harnessing under the Jiaozuo-Jincheng expressway,in order to correctly evaluate its quality and effect,we carried out a monographic study for the engineering by drilling, geotechnical testing, comprehensive geophysical prospecting and deformation monitoring.On the practical basis,gave out a profound of effectiveness for varied methods.In the comprehensive geophysical prospecting,we put forward a new idea to evaluate grouting effect by the use of high-resolution seismic reflected wave energy factors,and recommended evaluating indicators of varied goaf harnessing effectiveness detection methods, as well as detection method optimized integrated mode aimed at different engineering characteristics.
