田螺山遗址是我国第一处实行原址保护和展示的南方古遗址,发掘后打破了遗址原来所处的稳定环境,导致遗址出现了一些病害。为了使得该遗址较好地保存下去,本文分析了该遗址土壤的理化性质,在此基础上,选用CB材料对该遗址土样进行了室内及现场加固试验。加固前后土样耐水性、PH值及强度等表征的对比表明,加固后的土样具有较好的耐水性,抗剪强度参数粘聚力有明显的增大,从而增加了土壤颗粒之间的粘聚力。现场小面积加固试验表明,保持了遗址原貌,渗透性好,未见表面开裂现象,同时强度也有很大的提高。
Tianluoshan Site is the first ancient site in the South to be protected and displayed in the original site of our country. After the site was excavated, the stable environment in which the site was originally located was broken, resulting in some diseases at the site. In order to keep the site well, this paper analyzes the physical and chemical properties of the site soil. On this basis, the CB material is selected for indoor and site reinforcement experiments. The comparison of soil water resistance, PH value and strength before and after reinforcement show that the soil samples after reinforcement have better water resistance, shear strength parameters cohesion significantly increased, thus increasing the soil particles between Cohesion. Small-area reinforcement test showed that the original site of the ruins was preserved and the permeability was good. No surface cracking occurred while the strength was also greatly improved.
