摘要
运用地质雷达对忻州—保德高速公路官地坪2号隧道进行衬砌厚度和衬砌背后空洞检测,对检测数据进行统计分析,得到衬砌厚度偏差值分布规律,明确了衬砌厚度及衬砌背后空洞在衬砌施工中较难避免,建议公路工程质量验收规范对衬砌厚度验收条件适当放宽。
Based on the ground penetrating radar, test the thickness and cavity behind secondary lining of Guandiping No. 2 tunnel in Xinzhou to Baode expressway, analyze the test data, obtain the distribution of thickness deviation, the lining cavity behind lining thickness and is difficult to avoid in the lining construction, propose highway code for acceptance of construction quality of appropriate relaxation of lining thickness accept- ance conditions.
