摘要
基于塑性流动理论建立梯形截面有限土体被动土压力计算模型,揭示梯形截面有限土体被动土压力与半无限空间被动土压力的比例关系及模型参数对之的影响规律,并通过对某基坑支护加固工程的朗肯土压力理论及模型计算结果的对比及案例分析,论证梯形截面有限土体被动土压力对基坑(边坡)稳定的作用,验证模型的计算结果。
Based on the theory of soil plasticity,a model of the passive earth pressure from trapezoodal-cross-section finite soil body was built.The proportional relation and the effect of the model parameter on relationship between the passive earth pressure from trapezoodal-cross-section finite soil body and half-space passive earth pressure were researched.A reinforcing deep excavation was designed in Rankine theory and the model introduced in the paper.The effect of the passive earth pressure from trapezoodal-cross-section finite soil body on the stability of deep excavation and municipal slop was revealed,which verified the calculation results by the model.
