摘要
采用FLAC3D软件开展深基坑双排桩+锚索支护及开挖全过程数值模拟研究,给出开挖过程中和开挖结束后的应力和位移分布,监测变形状态,剖析开挖过程对基坑土体的影响,验证设计方案的可行性,及时调整现场施工的支护参数和支护措施.研究方法和结论对类似软土地区基坑工程的设计和分析有较大借鉴意义,监测点位移分析结果可为进一步开展反分析和二维分析提供依据.
FLAC3Dsoftware is used to develop the numerical simulation study on the excavating and supporting process of double-row piles plus anchor;the stress field and displacement field distribution along excavation and after the excavation are given;the state of deformation is monitored,the impacts of foundation pit excavation process on soil are analyzed,the feasibility of the 2D software design scheme is verified,and the supporting parameters and measures of construction are adjusted in site.The research methods and conclusions have significance for the similar design and analysis of foundation pit in soft soil area.The monitoring displacement analysis results can provide the basis for further analysis and two-dimensional analysis.
