Method for improving anti-overturning safety of existing balance weight type retaining wall based on side width structure
The invention discloses a method for improving the anti-overturning safety of an existing balance weight type retaining wall based on a side width structure, which is characterized in that the side width structure is adopted to reinforce the existing balance weight type retaining wall, wherein the parameter design of the side width structure comprises the steps of introducing an original design anti-overturning evaluation coefficient, an actual anti-overturning evaluation coefficient and a target anti-overturning evaluation coefficient, and calculating parameters of the side width structure ina reinforced moment model. Compared with the prior art, the brand-new calculation design method considering the bearing effect of the existing balance weight type retaining wall is provided for the existing balance weight type retaining wall adopting the side width structure, dismantling and reconstruction of the existing retaining wall are avoided, the size of the side width type retaining wallis optimized, and therefore on the premise that safety is guaranteed, engineering investment is reduced, and economical efficiency is improved.
本发明公开了基于帮宽结构提高既有衡重式挡墙抗倾覆安全性的方法，其特征在于，采用帮宽结构对既有的衡重式挡墙进行加固；其中，所述帮宽结构的参数设计包括：引入原设计抗倾覆评估系数、实际抗倾覆评估系数、目标抗倾覆评估系数，计算加固后力矩模型中的帮宽结构的参数。相比较于现有技术，提供了针对既有衡重式挡墙采用帮宽结构的一种考虑既有衡重式挡墙承载作用的全新计算设计方法，避免了既有挡墙的拆除重建，对帮宽挡墙的尺寸进行了优化，从而在保证安全性的前提下，降低了工程投资，提高了经济性。
