中文摘要	在室内实验条件下,向遗址土中掺加不同质量分数、不同类别的盐分,通过声波检测仪测定各试块的纵波波速,同时根据弹性力学理论计算出动弹性力学参数,分析了盐分质量分数和含盐类别影响遗址土纵波波速特性机理.研究表明:在外界恒定温度、恒定相对湿度以及含水率一定的条件下,掺人盐分为硫酸钠和硫酸钙试块的纵向波速与盐分质量分数呈正线性相关关系;而掺入氯化钠盐试块的纵向波速与盐分质量分数呈负线性相关关系.研究结果可为西北干旱地区的土遗址病害及对其加固修复提供动力学依据,也可为盐渍土中的声波探测技术提供参考
英文摘要	Under the experiment conditions in the laboratory, salt of different content and different types were added into the soil samples. The p-wave velocity of each test piece was mensurated by ultrasonic measuring system. At the same time, dynamic elastic mechanical parameters were calculated by the elasticity theory, and then the characteristics and mechanism of the influence of salt content and salt category on the p-wave velocity of soil samples from ancient ruins were analyzed. The research result shows that, under the conditions of constant temperature, constant humidity and constant moisture, the p-wave velocity of the test piece which has been blended with sodium sulfate and calcium sulphate has a positive linear relevant relation with the increase of the salt content concentration; but the test piece blended with sodium chloride has a negative linear relevant relation with the increase of the salt content concentration. The results could provide a dynamic basis for protecting the rare ancient earthen sites in northwest China; meanwhile, it could offer a, reference for acoustic detection in saline soil
