摘要:
为研究托换工程对上部砌体结构的影响,将上部墙体简化为深梁模型,考虑了墙体弹性模量与剪切模量比值的变化、中性轴位置的变化,推导出了将墙体沉降比和应变结合起来的墙体允许沉降公式,该公式可根据上部结构材料性能的变换得到不同允许沉降值,可更灵活的用于顶管施工对上部结构的影响分析
Abstract:
The effect of pipe jacking construction on the settlements of is analyzed with the upper masonry structure, the upper wall simplified to a deep beam. The ratio of elastic modulus to shear modulus and the location of neutral axis are considered, and the allowable settlement formulas combined with settlement and strain are deduced, by which the different allowable settlements can be obtained according to different material properties. The formulas can be used to analyze the effect of pipe jacking construction on the settlements of the upper structures flexibly
