| 英文摘要 | In this study, the governing equation for one-dimensional large strain consolidation of soft soils under electro-osmosis-surcharge preloading is derived with some assumptions, and the general analytical solution is proposed for the first time by using the methods of algebraic transformation and separation variable. The expressions for the specific analytical solutions under several common cases in foundation treatment are developed. Besides, the correctness of the proposed analytical solutions is verified by comparing them with the existing analytical solutions and finite difference solution. Finally, based on the proposed analytical solutions, the effects of effective voltage V-m, the ratio of electro-osmosis (EO) conductivity to hydraulic conductivity k(e)/k(v) and volume compressibility coefficient m(v1) on the consolidation behaviors are analyzed. It is found that the increase of V-m increases the absolute values of excess pore water pressure (EPWP) and hence the settlement increases. Furthermore, the increasing ratio of k(e)/k(v) leads to larger absolute values of EPWP generated in the soil, resulting in an increase of settlement. The consolidation degree U-s defined by settlement based on small strain and large strain models decreases with the increase of m(v1), and both the differences of U-s and settlement between the two consolidation theories increase with the increase of m(v1). In conclusion, the proposed analytical solution is simple in form and practical, which can be adopted to analyze the one-dimensional large strain consolidation behaviors under electro-osmosis-surcharge preloading.
