地质雷达在石质文物渗水病害探测中的应用

Application of geological radar to investigate seepage disease of stone heritage

阳华岩摩崖石刻为全国重点保护文物,目前石刻存在多种病害,主要有危岩体崩塌,石刻风化,岩体开裂、渗水及石刻表面污染等。本文在现场地质调查的基础上,采用地质雷达法对阳华岩摩崖石刻上部山体内部岩溶发育和裂隙分布情况进行了探测。探测结果表明,阳华岩摩崖石刻上部山体岩体破碎,岩溶裂隙发育,存在贯通的渗流通道,亟需对石刻上部岩体采取加固措施,防止病害进一步恶化。本次地质雷达探测在石质文物渗水病害勘查中应用效果良好,可为进一步采取防治与保护措施提供技术支持。

Yanghuayan Cliff Inscriptions is one of the national key historical and cultural relics. There are now a variety of diseases in the cliff inscriptions including dangerous rock,weathering,cracking,seepage and surface pollution. Based on regional engineering geology survey,the karst development and fissure distribution in the upper part of Yanghuayan Cliff Inscriptions are investigated using geological radar. The results show that the upper rock mass of Yanghuayan Cliff is fractured and the fissure is developed,and the seepage channel is interconnected. It is urgent to take measures to the upper rock mass to prevent the disease worsens. The geological radar detection has been proved a good effect in the stone heritage seepage disease survey. The detection results can provide technical support for later prevention and protection measures
