明挖地铁车站结构计算影响因素分析
The Analysis of Influence Factors for Open-cut Subway Station Structure Calculation
摘要
Abstract
With reference to a open-cut station, a variety of main structure calculation models are established with ANSYS parametric design language APDL. The influences of various factors on the calculation results are compared in the process of structure calculation, including main structure form, stratigraphic layer, palisade structure, calculation mode dimension, concrete strength of five aspects and qualitative analysis of other influencing factors. The results show that palisade structure influence on structure is obvious, especially on the sidewall; in case of clear difference in layers, the inner force in base plate and sidewall becomes more different if weighted average is used continuously for earth pressure calculation; the concrete grade poses less impact on the structure, but local inner force deviation may occur with but limited impact. Finally, suggestions to deal with structural design are put forward based on above factors.关键词
