本文介绍了利用火电厂排灰混合料桩进行地基处理的研究结果。采用有限元方法，研究了散体材料桩加固软土地基的沉降特性和固结过程。在论文的第一部分中，显示了材料的机械性能。进行了几个实验室测试，以校准用于数值模拟的材料模型。提出了软土时变特性的“各向异性粘-亚塑性”材料模型。第二部分介绍了该模型的标定过程。数值研究的结果进行了介绍和讨论。
In this paper the results of the study about ground improvement using piles of ash mixed material discharged from the thermal power plants are presented. Using Finite Element Method, the study investigates the settlement behavior and consolidation process of an improved soft soil layer using granular column. In the first part of the paper, the mechanical properties of the materials are shown. Several laboratory tests are performed to calibrate the material models using in the numerical simulations. The material model “Anisotropic Visco-Hypoplastic” for the time dependent behavior of the soft soil will be presented. The calibrate procedure of this model is explained in the second part of the paper. The results of the numerical investigation were presented and discussed.
