摘要:
首先简要回顾了土的电阻率影响因素,介绍了电阻率静力触探(RCPT)测试技术和操作方法,采用RCPT在连云港海相粘土场地进行了现场试验,获得土的原位电阻率测试值.结合连云港海相粘土的沉积特性与物理化学分析试验,对RCPT电阻率测试数据进行了基于矿物成分、离子浓度、Fe3+含量影响因素分析.研究发现:土的电阻率随着粘土矿物含量和离子浓度的增加而减小,并且Fe3+对电阻率测试值也具有明显的影响.分析表明:连云港海相粘土的沉积特征和化学特性对其电阻率测试参数具有显著的影响.
Abstract:
The factors affecting soil resistivity are reviewed briefly in this paper. Measuring equipment and operation principle of the resistivity cone penetration test(RCPT)system are introduced. The field RCPT tests were carried out at Lianyungang marine clay sites and the in-situ resistivity values were obtained. According to the depositional characteristics and ionic chemistry examinations, some factors affecting RCPT results are analyzed in terms of some literatures. It is shown that the electrical resistivity decreases with increasing clay mineral percentage and ion concentration. The Fe3+concentration is also the indicative factor affecting the resistivity values. The results obtained from field RCPT measurements and chemical analysis show that the depositional characteristic and chemistry properties have obvious influence on resistivity of Lianyungang marine clay.
