The results show that the gabion meshes present good tensile characteristics in the event of the rupture of the meshes. The larger-diameter gabion mesh shows a better mechanical performance, and the mechanical performance of 80RE geogrid is superior to that of 70RE geogrid. The revised relationship curves between the tension per unit width and unit elongation also present elastic stage, yield stage and strength stage. The constraint deformation of reinforcement is influenced by factors such as secant modulus of materials, stress levels, and the length of reinforcement in active area and stable area.

On the basis of making it clear that laterization includes such three integrated stages as weathering, micro-granularity and soil formation of laterite, the thesis illuminates characteristics of Kunming laterite in chemical composition, physical mechanics, composition of granules, fractal dimension of granularity and the connection of granules. The experiment using soil reinforced agent to solidify the laterite shows that the mechanical traits of laterite have been improved because of its involvement, the best compact indicators and shear strength ones increased and the indicators of laterites penetrability and compression decreased. The effects of reinforcement can be weighed through its coefficient and the mechanism of reinforcement can find the explanation in the effect of soil reinforced agent on the laterite granules, the changes in the electric double layer caused by soil reinforced agent and its enwrapping of laterite granules.

This means that the residual strain in rolled alloy promoted the aging process. The influence of aging temperature on the room-temperature mechanical properties of 1〓, 2〓 and 6〓 alloys was tested and the results show that the 1〓 alloy without minor element additive is very sensitive to the aging temperature. Over-aging occurred easily when the aging temperature is somewhat higher, so it is difficult to control the aging treatment in production. The 6〓 alloy with combined Mg, Cr, Co additives showed less tendency of over-aging, the alloy can be aged in a wider temperature range and the mechanical property is stable. So the treatment process can be easily controlled.

对不同微量添加元素的1〓、2〓和6〓三种合金经热轧态时效后的室温力学性能表明，不添加微量元素的1〓合金对时效温度较敏感，温度偏高时容易产生过时效，且过时效的温度明显低于加Mg的2〓合金和同时加Mg、Cr、Co的6〓合金，这对生产过程中的工艺控制增加了难度，6〓合金的过时效倾向最小，合金可以在较宽的温度范围内进行时效，力学性能较稳定，使生产工艺较易控制。
