| 摘 要： | 根据沪瑞国道主干道线坝陵河悬索大桥西锚洞勘察试验资料,本文论述了碳酸盐岩软弱夹层的物理力学性质。研究表明,这类夹层及其粘土物质系顺碳酸层间溶蚀-交代的产物。其物理-力学性质试验证实:夹层的粒度分析属红粘土的范畴;其抗剪强度与现代红粘土相似,也与其他类型的软弱夹层相似。

| Abstract: | According to the date of exploration and test in west anchoring tunnel at Balinghe River suspension bridge, the properties of weak intercalation in carbonate rocks are discussed in this paper. The research have proved that the genesis of this kind of clay and intercalation is a solution- replacement products in carbonate rocks. The physical and mechanical testing shows that the grain size analysis of intercalation is belong to the size of red clay, the shear strength of intercalation is similar with the strength of recent red clay and is also similar with other kinds of intercalation. |
