瞬态面波法在岩溶路基注浆质量检测中的应用研究

摘要

铁路客运专线修建在岩溶地区时，需要对岩溶地基进行加固，岩溶地基注浆这种地基加固方法得到广泛应用。为了验证注浆效果，需要对其进行检测。本文重点介绍瞬态面波法的原理及其在沪昆铁路贵州段注浆质量检测中的应用。瞬态面波法具有操作方便、快速、分辨率高等特点，且有相应的判定标准，能保证检测质量。本文应用实例表明，瞬态面波法是高效、可行的测试方法。%In the construction of passenger dedicated railway,foundation reinforcement stands as a necessary precaution for karst-area section. T herefore,the approach of karst foundation reinforcement is widely adopted in railw ay engineering,w hich requires quality inspection afterw ards. U nder such background,the paper explains in detail the transient surface wave method and its application to the Guizhou section of Shanghai-Kunming line. It has been verified that the approach stands out for its straightforward workflow,speedy operation and high resolution, and with a well-established criteria,it delivers a satisfied performance in quality inspection. W ith this in mind,the paper cites practical examples in its discussion in an effort to prove that transient surface wave method is efficient and therefore applicable.
