潮湿环境黏性土地区考古现场地下水控制试验研究

Experimental Research on the Technology of Underground Water Control Applied to Archaeological Sites in Cohesive Soil Regions in Humid Environments

针对黏性土地区考古现场地下水排水困难的问题,采用了构筑人工填砂导水排水沟的方法,在考古探方周边形成导水排水体系。现场模拟试验证明,该方法不仅能够排除黏性土中的地下水,而且能够隔断毛细水运动,从而有效控制地下水位,防治考古探方渗水,保障考古工作顺利进行。该方法同样可用于潮湿环境地下水浅藏地区的遗址保护和陈列馆渗水防治。

This study aims to solve the problem of underground water drainage happening in archaeological sites in cohesive soil regions. The method is to build drainage ditches artificially filled with sand so as to form a drainage system surrounding tombs under excavation. Experiments show that this method is useful for the discharge of underground water from cohesive soil and the obstruction of capillary action, which will efficiently control the underground water level and protect the tomb from water seepage, thus ensuring the proceedings of archaeological work. The same method can be used in the shallow underground water of humid environments,not only for the conservation of ancient sites, but also for preventing seepage in galleries.
