摘要
随着当前基础建设的发展,经常遇到在采空区上修建的问题,而评价采空区加固处理效果则成了关键问题,当前国内外在采空区治理效果检测方面方法手段甚多,但尚没有成熟可靠的技术方法,国内外对其处治技术尚未形成系统,也未建立相应的技术规程或行业标准,本文总结了当前一些应用比较广泛的检测手段,分析各自的优缺点,结合具体工程提出采用钻孔检测、电测深法与电磁CT法、变形监测4种方法综合检测模式。
With the current development of foundation construction, the building construction on the mined-out area is usually encountered, and the evaluation of effects for mined-out area reinforcement becomes the key issue. There are many methods to inspect the effect of the mined-out area treatment at home and abroad, but a mature and reliable technique has not been formed. The treatment technique for mined-out area and the corresponding technical regulations and standards have not been established systematically. Some widely-used measures to inspect the treatment effect are summarized, and the advantages and disadvantages of the measures are analyzed. The comprehensive inspecting mode consisted of drilling detection, electronic sounding, electromagnetic CT and deformation monitoring is proposed.
