龙门石窟敬善寺区域水害治理探讨

A Discussion on Flood Damage Control in Jingshansi Cave of Longmen Grottoes

在自然因素和人为因素的作用下,龙门石窟发育有围岩崩塌、雕刻品风化、洞窟渗漏及衍生病害等病害。通过调查与分析,敬善寺区域水害主要水源为大气降水,破坏方式为洞窟渗漏和坡面径流。截断大气降水入渗洞窟路径,采用裂隙灌浆和地表防渗相结合的方式进行洞窟渗漏治理。要修建合理的地表排水系统,将大部分的坡面径流通过系统快速排出区域,从而达到保护文物的目的。

The Jingshansi Cave,an important component of the Longmen Grottoes,is of high heritage value.Due to natural disasters and poor management,damages of varying extent such as wall rock collapse,weathering sculptures,cave leakage and like,can be seen in the cave.Based on the investigation and analysis of flood damages and fissures,mainly from leakage and slope runoff caused by heavy rains and storms,the paper intends to put forward some possible solutions to deal with the damage.It is advised to combine measures of crack grouting and water-proofing surface to prevent roof leaking and to improve the drainage system to dredge the rainwater from the slope runoff so as to achieve the aim of protecting valuable cultural relics.
