【摘要】 新建铁路长沙至昆明的贵州关岭车站区间段岩溶路基,必须进行注浆加固。为检查加固效果,注浆加固处理后,采用电测深法和瞬态面波法综合检测,并辅以钻孔取芯验证,检测效果较好。实践表明,在路基注浆质量检测工程中,直流电测深和瞬态面波综合法检测是不错的方法组合,应用效果较好。更多还原

【Abstract】 The karst subgrade,which lies in the interval section of Guizhou-Guanling Station on the newly built railway from Changsha to Kunming has to be reinforced by grouting. In order to check the reinforcement result,the combination of electrical sounding and transient surface wave method was used by the aid of core drilling for verification,and the result was proved to be good. Therefore,it is demonstrated by practice that the DC sounding together with transient surface wave method is a better combination in grouting quality inspection,and the application result is good.更多还原
