Abstract

Lime has powerful characteristics of hygroscopicity, expansibility and gelation with soil, so a slope can be strengthened by placement of lime piles. In this paper, experiments have been performed to investigate the diffusion characteristic of lime in loess, and the influence of lime to the physical and mechanical properties of loess also have been examined, in order to verify the feasibility of using pile to improve the stability of slope. The results show that it is feasible to improve stability of slope by lime piles. Pile spacing should be set about 8.5 times as many as the diameter of the pile when the pile holes arranged according to the plum flower form from this test. Moreover, lime piles strengthen the loess slope mainly by gathering and cementing the clay grains in loess.
