| 摘 要： | 有限元软件数值模拟是现在从业人员分析敏感环境下基坑工程的重要手段,选择合适的本构模型是其关键。为了解工程中常用的三种土的本构模型适宜性,运用三维有限元软件Midas GTS NX模拟了某大型深基坑开挖过程,将采用不同本构模型的数值模拟结果与基坑监测结果进行对比,进而分析本构模型的适用性。可为本区类似工程进行有限元数值模拟分析时提供参考和借鉴。

| Abstract: | Finite element software is an important means for engineers to analyze the foundation pit in sensitive environment by numerical simulation,and the key of numerical simulation is to select appropriate constitutive model.In order to understand the suitability of three soil constitutive models commonly used in engineering,the excavation process of a large deep foundation pit is simulated by using Midas GTS NX three-dimensional finite element software.The numerical simulation results of different constitutive models are compared with the monitoring results of foundation pit,and then the applicability of the constitutive model is analyzed.It can be used as a reference for similar projects in this area in finite element numerical simulation analysis. |
