TL;DR: In this paper, the potential of lime on strength and bearing capacity improvement of subgrade soil is studied. But beyond an optimum lime content, opposite trend is observed. And the strength improvement of lime stabilized soil is further enhanced with curing time.
Abstract: This paper attempts to study the potential of lime on strength and bearing capacity improvement of subgrade soil. The effect of soil type, different lime percentages (3, 5, 7 and 9%) and curing duration (0, 7, 14 and 28 days) on the engineering properties of soil is evaluated by conducting series of laboratory tests such as linear shrinkage, unconfined compressive strength (UCS), split-tensile strength (STS) and California bearing ratio (CBR) test. The result indicates that soil with large clay fractions needs a relatively higher percentage of lime to alter their physicochemical characteristics. Addition of lime reduced the linear shrinkage strains and increased the UCS, STS and CBR value of soil. But beyond an optimum lime content opposite trend is observed. The strength improvement of lime stabilized soil is further enhanced with curing time. Moreover, the micro-structural analyses are performed to understand the mechanisms involved in the lime stabilization process. Change in soil morphology fr...

TL;DR: In this article, a finite element analysis has been carried out using Plaxis 3D vAE.01 to investigate the ultimate bearing capacity of isolated and interfering surface strip footings placed at the crest of the c-φ soil slope.
Abstract: Estimation of the bearing capacity of a shallow footing located at the crest of a slope is an intricate problem. The problem becomes much more complicated when multiple numbers of closely spaced footings interact with each other while resting on the slope. In this regard, a sequence of finite-element analysis has been carried out using Plaxis 3D vAE.01 to investigate the ultimate bearing capacity of isolated and interfering surface strip footings placed at the crest of the c-φ soil slope. In the numerical analysis, the influence of different geo-parameters on ultimate bearing capacity has been studied. From the failure mechanism, it has been observed that the impact of slope and the influence interference disappeared above a critical setback ratio (b/B) of 6 and beyond a critical spacing ratio (S/B) of 3 for single and interfering strip footings located at the crest of slope, respectively.
