摘要

针对红黏土地区地基排水固结过程的复杂性,对红黏土地基排水固结沉降进行数值分析。采用大型通用有限元分析软件ABAQUS/Standard中的固结计算模块Soils和自带的修正剑桥模型,以某铝厂的改造工程项目为算例,对红黏土地基中的沉降随时间的变化规律、孔隙水压力消散规律、孔隙比随深度的非线性分布以及土体的有效应力增长进行了研究。研究表明:计算结果与土力学规律吻合,能准确反映红黏土地基固结沉降的实际情况,可为红黏土地基上的建(构)物改造工程地基处理和工程设计提供参考。

Abstract

Due to the complexity of drainage consolidation of red clay foundation, we simulated and analyzed the consolidation settlement by using the consolidation calculation module Soils and modified Cambridge model of ABAQUS/Standard. The reconstruction project of an aluminum factory was taken as an example. The variation of red clay foundation’s settlement with time, the dissipation of pore water pressure, the non-linear distribution of void ratio with depth, and the effective stress growth of soil were researched. Results suggest that the calculated results are in good agreement with the law of soil mechanics, and the actual situation of the red clay foundation consolidation settlement could be reflected accurately. This research provides references for the foundation treatment and engineering design of buildings on red clay ground.
