FLAC3D在复杂工程条件下的应用

Application of FLAC3D Under Complex Engineering Conditions

利用建筑垃圾堆山造景是现代城市的一个新方向。但由于堆山工程占地范围大,荷载大,往往会产生一系列的工程地质问题,在软土地区这个问题更为突出。为使堆山工程能顺利进行,必须对地基进行一定的处理,而常规计算只能选择典型剖面或者地段进行局部分析,不能反映真实的三维影响特征,但数值分析可以有效解决这一问题。利用有限差分软件FLAC3D,对天津某堆山工程进行分析,为优化地基处理方案提供有力依据。

The use of construction waste is a new direction to build mountains and landscapes for modern cities. However the large area of the mountainous project and the largely load, a series of engineering geological problems are often generated. This problem is more prominent in soft soil areas. In order to make the mountain stacking work smoothly, the foundation must be processed to a certain extent,while the conventional calculation can only select the typical section or section for local analysis, and can not reflect the real three-dimensional influence characteristics, but numerical analysis can effectively solve this problem. In this paper, the finite difference software FLAC3D is used to analyze a certain mountainous project in Tianjin9 which provides a strong basis for optimizing the ground treatment plan.
