| 摘 要： | 河南洛阳龙门石窟位于碳酸盐岩体中,易于溶蚀。近年来,石窟区伊河水以及雨水中Cl-、SO2-3等有害离子明显增加,加剧了石窟的岩溶病害。在龙门石窟溶蚀现4、NO-4、NH+状调查的基础上,从岩溶的空间分布规律、岩体结构渗水连通网络和微观结构等方面探讨了溶蚀病害的机理。提出治理龙门石窟溶蚀病害的根本途径是治水,应该通过裂隙注浆,设置地表防渗铺盖和地表排水系统等止水措施,杜绝雨水入渗到洞窟内溶蚀雕刻品。此外,对现有岩溶沉淀物可以采用软化剥离的方法进行人工清除,对雕刻品上的溶洞、溶沟等可采用石窟原岩岩屑调制的修复砂浆进行充填修复。

| Abstract: | The Longmen Grottoes are located in carbonate rock stratum.These rocks are easy to be corroded. The harmful hydroniums of Cl~-?SO~2-)4?NH~+4?NO~-3 and so on are obviously increasing in the Yihe river water and rainwater of the Longmen Grottoes area in recent years. The diseases of the grottoes have been taken a turn for the worse by these components. Rain water permeated through the earth's surface and seeped into the grottoes along the fracture channels and corroded the stone carvings.The karst holes, corroded grooves,gouges and bores with different sizes have been formed on the rock surface of the grottoes,which destroyed the integrality of rocks and the stone carvings.The sediments formed by karst have covered the stone carvings, which have made the stone carvings lose the original value.On the base of investigation of the status quo of the karsts diseases of the Longmen grottoes,in this paper the mechanism of the karsts diseases is discussed according to the spacial distributing regularity of karst,the penetrative connecting meshwork of the rock structures,microstructures and so on.The fundamental prevent method for the karsts diseases of Longmen Grottoes is to control water.The rainwater seeped into the grottoes which corroded the stone carvings should be put to prevent by fissure grouting, the pavement of ground waterproof,the installation earth's) surface drainage system and so on. Furthermore,the current sediment of karsts can be cleared away by the manual physical work of being soften and peel off.The current karsts holes and gouges can be filled up with the renovating mortar modulated by primary rocks chipping and mortar. |
