摘要:
为了分析与掌握矩形顶管施工引起的地表沉降变形规律,提出基于MIDAS-GTS有限元软件的分析方法,首先,通过工程实例验证MIDAS-GTS有限元软件在分析顶管施工引起地表沉降变形的有效性;其次,通过影响因素的敏感性分析确定不同影响因素作用下的地表沉降变形特性,这些影响因素主要包括开挖面支护压力、侧摩阻力、地层结构特性等;最后,通过地表沉降变形特性分析得出矩形顶管的适用范围。研究结果表明:基于MIDAS-GTS有限元软件的地表沉降规律分析方法和结果,可为矩形顶管施工过程提供相关参考和借鉴。
Abstract:
In order to analyze and master the ground settlement and deformation laws caused by the construction of rectangular pipe jacking, an analysis method based on the MIDAS-GTS finite element software was proposed. Firstly, the validity of analyzing the ground settlement and deformation caused by the construction of pipe jacking when using the MIDAS-GTS finite element software was verified through the practical engineering case. Secondly, the characteristics of ground settlement and deformation under the effect of different influencing factors were analyzed and determined through the sensitivity analysis of the influencing factors, which mainly included the support pressure of excavation face, side friction, strata structure features, etc. Finally, the application scope of rectangular pipe jacking was analyzed and obtained through the analysis on the characteristics of ground settlement and deformation. The results showed that the analysis method and results of ground settlement based on the MIDAS-GTS finite element software can provide the relevant reference for the construction process of rectangular pipe jacking.
