| 摘 要： | 基于"削坡减载"的思想,结合工程实际应用,提出了在堆载预压法处理中应用阶梯形堆载的方法,不仅保证了足够的抗滑安全系数,防止了地基滑移破坏,而且大大缩短了工期,最后,用软土地基堆载的塑性极限分析方法对全面堆载预压法与梯形堆载预压法处理软基时的稳定性进行了分析比较,其结果进一步证明了梯形堆载方法的合理性,提高了处理地基的稳定性和安全储备,加快了堆载速度,缩短了工期。

| Abstract: | Based on the "cutting bulk & reducing load" theory and combined with engineering application, echelon-shape loading method is put forward and used in preloading on soft foundation.With using this method, stability of soft foundation is improved and time needed for a project is shorten. At last, rationality of echelon-shape loading method is testified by the method of plasticity limit analysis, which implicit the stability can be improved with using the echelon-shape loading method. |
