【摘要】 本文在文献[1]、[2]给出的软土地基Biot固结的有限元构式及程序基础上,对某大型堆山工程分级加荷施工过程中,软土地基的固结变形,附加应力及超孔隙水压力分布,塑性区的开展等进行了弹性非线性有限元的计算分析,得出了在理论和工程应用上一些有意义的结论。本文的计算方法和结果,可供工程技术人员在类似工程的初步设计时借鉴和参考。有些内容尚可进一步研究和探讨。更多还原

【Abstract】 Based on the formulas and the program of elastic nonlinear F. E. M. for computing and analysing the Biot’ s consolidation on soft clay ground given in Ref. 1 and Ref. 2, this paper shows the consolidation diformation, distribution of additional stress and excess pore water pressure as well as develop-ment of plastic zone, these are computed, of the soft ground beneath an artificial hill with step-up looding during the constructional stage. Some useful conclusions in theoretic and engineering are obtained. The numerical method and concluaions of the paper are referenced for designing tentatively in similar engineering. Some problems would be further studied.更多还原
