中文摘要：

以20处土遗址的物理性质参数测试、易溶盐监测和气候环境研究的相关数据为基本依据,分别掺入不同含量Na2SO4和NaCl,并对经历干湿循环的遗址土重塑样进行强度实验,最后结合实验结果和定性分析对复合过程土遗址强度响应的规律与机理进行讨论。研究结果表明：遗址土的抗压、抗拉和抗剪强度对该复合过程产生明显的衰减性响应行为,试样的各种强度参数与掺入盐分的含量之间存在良好的相关关系,而且其回归方程服从指数法则。

英文摘要：

Based on abundant correlation data,such as physical testing,salinity monitors and the climatic environment research of twenty earth ruins,the strengths of reconstituted samples going through dry-wet circulation after being mixed with different content of common salt Na2SO4 and NaCl were tested.Finally,the regularity and mechanism of earth ruins intensity response with compound process were discussed.The results show that the compressive strength,tensile strength and shearing strength of ruins soil have obvious weaken responsing behavior to this compound process;intensity parameters have good relational dependence on the content of salinity,and moreover,the regression equations obey index principle.
