考虑土体非线性的内支撑支护体系优化设计

Optimal Design of Inner Bracing Supporting System Considering Soil Nonlinearity

考虑土体非线性,对内支撑支护体系进行优化设计。通过引入参数f、n,研究了支撑点位置及加撑前的开挖深度对支护体系的影响。讨论了竖向设一道撑的单排桩+钢管内支撑支护体系优化问题的解决方法,并给出了具有一定指导性的建议。

The inner bracing supporting system is optimized to design by considering the soil nonlinearity.By introducing the parameters f and n,the article studies the influence of the bracing point position and the excavation depth before the bracing is added on the supporting system.The article discusses the method to solve the optimal design of a vertical bracing pile bent + inner steel-pipe bracing supporting system,and gives some guiding suggestions.
