摘要:
为了避免地下隧道出现安全隐患,针对传统的计算方法在精度上不能满足实际要求的问题，提出了数值模拟计算的方法.基于快速拉格朗日方法的数值模拟软件FLAC3D在岩土工程计算中有着广泛的应用，然而在建模方面，该软件不够人性化，较难建立复杂模型.为弥补该软件在前处理功能上的不足，利用福传软件高速计算能力和数组内存可分配性，把模型从ANSYS转换到FLAC3D：首先利用ANSYS进行模型建立及网格划分，接着通过其内置的参数化设计语言调用模型数据, 然后使用福传编写的接口程序，将数据转换并导入FLAC3D完成分析.最后，建立武汉地铁三号线汉江过江地铁模型，47360个单元、50840个节点的模型转换只花了不到10秒的时间，验证了此方法的可行性与高效性.
Abstract:
The traditional calculation methods cannot meet the requirements of accuracy. To avoid security risk of subway, the method of numerical simulation was proposed. Numerical simulation software FLAC3D based on Fast Lagrangian method has been widely used to geotechnical engineering, but it is not good enough to build complex models. To make up for the lack of pre\|processing function of FLAC3D, the high\|speed computing ability and memory dynamic dispensability of Fortran were used to convert the complex model from ANSYS to FLAC3D. Firstly, ANSYS was used in the method to build model and mesh generation, then the model data built\|in ANSYS was derived by APDL language, and thirdly, interface program written in FORTRAN was applied to convert data to FLAC3D model. Eventually, the technique was applied in Hang River Tunnel of Line 3 of Wuhan Metro, the conversion of 47360 elements and 50840 nodes only took less than 10 seconds, which demonstrates that the method is feasible and efficient.
