| 摘 要： | 在分析粘性土磁效应机理的基础上,根据Ⅰ、Ⅱ级阶地河流冲积相粘性土的分布及其特性和孔隙水化学特性,尤其是孔隙水中的总铁含量以及铁离子的赋存形式,将南宁市邕江Ⅰ、Ⅱ级阶地河流冲积相粘性土初步划分为磁效应强化区、磁效应较弱区两个磁效应区.随着城市附加磁场的增大,磁效应强化区粘性土的强度将大幅度增加;磁效应较弱区粘性土的强度也将有所增加,但其增加的幅度不高.

| Abstract: | Based on analysis of magnetic effect mechanism of alluvial cohesive soil,according to the distribution and character of river alluvial cohesive soil of first and second terrace of Yongjiang River of Nanning,pore water chemical characteristic,especially total iron content in pore water and holding form of iron ion in pore water,this text preliminarily divides the river alluvial cohesive soil of first and second terrace of Yongjiang River of Nanning into two magnetic effect region: reinforced region and weaker region of magnetic effect.With the increment of superimposed magnetic field on city,the strength of reinforced region of magnetic effect of cohesive soil is increased by a big margin,and the strength of weaker region of magnetic effect of cohesive soil can also increase to some extent,but its increasing range will not be high. |
