岩土工程数值软件在工程中的应用已经得到了越来越多的重视,持续的改进使得计算软件得到不断的优化。应用岩土工程数值软件可实现地基土-桩-筏板-上部结构的整体建模,可以为桩筏基础共同作用进行精细计算,进而为岩土工程师提供更加可靠的分析数据,并为结构设计过程提供技术支持。结合北京Z15地块超高层建筑的桩筏计算分析实例,对PLAXIS和ZSOIL数值软件的建模过程、参数指标选取及计算数据分析进行全过程介绍,以期能为应用数值计算软件对桩筏基础开展精细计算,积累工程应用经验。
The application of geotechnical numerical software in engineering has gained more and more attention. The continuous improvement has made the calculation software continuously optimized. The geotechnical numerical software can be used to realize the overall modeling of the foundation soil-pile-raft-superstructure, and can be used for the detailed calculation of the interaction of the piled raft foundation. In turn, the geotechnical engineer can provide more reliable analysis data and provide the structural design Process to provide technical support. Combined with the example of piled raft analysis of Beijing Z15 high-rise building, the modeling process, parameter index selection and calculation data analysis of PLAXIS and ZSOIL numerical software are introduced in the whole process in order to develop the piled raft foundation for the application of numerical calculation software Fine calculation, accumulation of engineering application experience.
