摘要

摘要: 为了分析作用在钢板桩围堰上的土压力大小,以新建阜阳至六安铁路颍河特大桥深水基础钢板桩围堰施工实践为例,通过建立钢板桩、内支撑和土体相互作用的三维整体有限元模型,分析了钢板桩围堰施工过程中土体的应力状态、土压力大小及其发展变化规律。研究结果表明：钢板桩围堰施工过程中,周围土体没有达到极限平衡状态;作用在钢板桩围堰外侧的土压力介于主动土压力和静止土压力之间,并靠近静止土压力;而作用在钢板桩围堰内侧的土压力介于静止土压力和被动土压力之间,并靠近静止土压力;考虑到钢板桩围堰工作状态的土压力难以准确确定,建议设计计算时钢板桩围堰内外土压力均采用静止土压力,计算结果偏于安全。

Abstract: In order to analyze the earth pressure acting on steel sheet pile cofferdam, the construction practice of deep-water foundation at Yinghe River Bridge of newly-built Fuyang-Lu’an Railway is investigated. Three-dimensional finite element model is established considering the interaction among steel sheet pile, internal bracing and soil layer. The values and change rules of earth pressure are analyzed during the construction process of steel sheet pile cofferdam. The results show that the surrounding soil does not reach limit equilibrium state during the construction process of steel sheet pile cofferdam. The value of earth pressure on the outer steel sheet pile cofferdam is between the active earth pressure and the static earth pressure, which is close to the static earth pressure. The value of earth pressure on the inner steel sheet pile cofferdam is between the passive earth pressure and the static earth pressure, which is close to the static earth pressure. The earth pressure on steel sheet pile is suggested to use the static earth pressure because it is difficult to accurately determined under working condition. The suggestion will make the design results be safer.
