浙江萧山跨湖桥独木舟遗址加固保护试验研究

为了保证所用加固材料对跨湖桥独木舟遗址土壤加固的有效性,使用改性水性环氧和正硅酸乙酯两种加固材料,分别于该遗址隐蔽部位进行了小面积加固试验,通过测试加固前后的土壤密度、pH值和色差以及强度等,对加固效果进行了评价。结果表明加固后的土壤干密度有所提高,土壤更加密实,仍处于原来的中性环境,保持土壤原貌,抗剪强度也有所提高。

Conservation and reinforcement of the Kuahuqiao canoe site ofXiaoshan, Zhejiang province

In order to ensure the reinforcement of the Kuahuqiao canoe site, field test experiments were done, namely by applying modified water epoxy and ethylsilicate agent separately to small areas of concealed parts of the site. Results were evaluated by measurement of density, color change, pH value and strength of the treated parts. These experiments showed that the soil sample treated with the modified water epoxy showed excellent in reinforcement effects, resulting in higher density and shear strength without pH or color change.
