摘要
通过对安徽地区粉土的室内改良试验,从试验的角度对不同的掺灰剂(水泥、石灰)及不同配合比改良后粉土的性质进行分析。研究改良后粉土CBR(承载比)值及无侧限抗压强度与龄期及配合比的关系,并根据室内试验的结果,提供经济合理的方案;通过对改良后粉土CBR值和无侧限抗压强度的比较,认为两者对于判断材料强度具有相关性,由试验结果拟合得到两者的关系。
Through the indoor amelioration test of silt in Anhui, experimental research is carried out to study the property of silt improved with different dose of admixture such as cement and lime. According to the improvement test in the laboratory, the relationship between CBR value, unconfined compression strength of silt and curing day, match dose is found and rational scheme is offered for practical construction. By comparison of CBR value with unconfined compression strength of improved silt, it can be found that CBR and unconfined compression strength are related to the judgemwnt of the strength of material, and the their relationship is obtained according to the test results.
