通古斯巴西古城遗址土体特性及PS加固试验

通古斯巴西古城遗址是新疆重要的土遗址之一,原为唐龟兹驻兵的安西都护府所在地。遗址中曾出土大批文物,对于研究西域的屯垦历史和古代城址布局等有重大意义。为了系统地研究了通古斯巴西古城遗址土的工程特性,在实地调查的基础上,通过室内试验对通古斯巴西古城遗址土的物理、力学、水理和化学性能进行测试。此外,还测定了不同PS浓度加固后遗址土重塑土块抵抗风蚀雨蚀能力的差异,进一步确定了PS的渗透加固措施对土质文物的防风化及雨蚀效果。结果表明,7%的PS溶液防风化抗雨蚀效果要更为显著。研究结果可为PS的施工应用提供依据。

Soil characteristics of Tonggusibaxi ancient city and site reinforcement using potassium silicate solution

Abstract:Tonggusibaxi Ancient City, one of the most important earthen sites in Xinjiang, was a military stronghold of Anxi Frontier?Command in Qiuci during the Tang Dynasty. A large number of cultural relics, having great significance for studies of the cultural history and city layout in the Western Regions in the ancient times, have been unearthed from the site. As described in this paper, during an onsite survey the physical,chemical, mechanical and hydrological properties of the soil were tested in Tonggusibaxi Ancient City. In addition, the anti-erode properties of the soil were tested, after it had been reinforced concentration using potassium silicate(PS)solutions of various concentrations, under rainy and windy conditions. The experiments confirmed that PS could be used to reinforce earth sites and on-site reinforcement projects.
