高速公路下伏采空区治理质量监控技术试验研究

Study on Inspecting Techniques Applying to Mined out Area Treatment Involved Expressway Project

高速公路下伏采空区治理工程的监控技术对于确保工程质量至关重要。在某采空区注浆充填法治理工程中应用多种方法对注浆过程和注浆效果进行了监控 ,包括综合物探法、钻探、压水试验和变形观测。测试结果表明 :以综合物探、变形观测为主 ,结合少量钻孔进行监控的模式是有效的。

The inspecting techniques are important to ensure the quality of mined out area treatment involved expressway project. In order to inspect the grouting process effect,many methods are applied to the grouting including high density resistivity method,drilling,pump in test and deformation observing.Testing results show that the inspecting mode of comprehensive geophysical method combined with deformation observing and a few boring is effective.
