摘要
本文对云南鲁布格堆石坝心墙红土料进行了宏观和微观试验。试验表明,红土的力学性质好,而物理性质与力学性质二者之间相互矛盾不一致。同时证实了红土中团粒结构和定向效应的存在,说明红土中具有多孔集合体的特征。利用红土的微观结构观点解释了物性和力性之间的不一致现象,特别是对其应力～应变～体变曲线出现的特殊现象从本质上进行了阐明。
This paper descibes the macrotest and the microtest of laterite for rock- fill dam of Lubuge Hydroelectric power station in Yunnan province.The tests show that the physical property of laterite and its mechanical prnperty are contradictory and inconsistent.The tests have primarily proved the existence of cluster structure and directional effect,and explained the feature of eaterite’s being porcus congregate mass Appling the theory of microstructure of later- ite,it has explained the contradictery phenomena between physical property and mechanical property,particularly,the special phenomena of stress-strain- volumetric curve for laterite has been discussedin detail.
