Field tests on grouting effect of karst roadbed based on transient Rayleigh wave method

(School of Civil Engineering, Southwest Jiaotong University, Chengdu 610031, China)

摘要

摘要: 为深入研究瞬态瑞雷面波法在岩溶路基注浆质量检测中的应用，现场选取 12 段试验测区，采集 1470 个测试样本点，其中在 4 个重点测区中进行注浆前后的对比测试及部分注浆后长时间追踪测试，在其余 8 个测区中进行验证性测试。结合现场压水试验及钻孔取芯等多种验证手段，基于有效试验样本数据分别建立岩洞、岩体、土体 3 种不同地下介质的瞬态瑞雷面波法注浆质量检测标准，并确定合理的检测时间为注浆完 7 d 后。经部分验证性试验测区内回判试验表明，试验结论准确可靠。

Abstract: To deeply study the use of transient Rayleigh wave method for detecting the grouting effect of karst roadbed, 12 sections in the field test area are selected, and 1470 test sample points are collected. The comparative tests on 4 important test areas before and after grouting and long-time trace tests are carried out. The confirmative tests on other 8 test areas are performed. Combined with the multiple confirmative methods of field water pressure tests and borehole coring and based on the effective test data, the criteria for detecting grouting effect of three different subsurface media such as cave, rock mass and soil are proposed by means of the transient Rayleigh wave method, and the suitable detecting time is 7 days after grouting. The confirmative tests show that the results are credible.
