【摘要】：提出对长春市城郊低层高密度建筑施工中的绿色挡土墙进行设计。首先,将新型绿化挡土墙的基础构造、受力荷载等方面与传统挡土墙实行比较分析,利用新型计算模式,设定不考虑地表均布荷载的条件下,根据填土重量生成恒载土压力,运用库伦主动土压力进行计算并引入增大系数,使土压力分布形成折线型。其次,以长春市某建筑工程的挡土墙为现场实验,对加筋挡土墙进行受力测试。实验结果表明:绿化挡土墙在施工及完工后,墙内拉筋受力范围小于总断裂拉力,拉筋受外力时呈线性变化,土压力呈现近似抛物型变化,证明了新型挡土墙计算模型设计可行性较高。
[Abstract]:This paper presents the design of green retaining wall in the construction of low-story and high density buildings in Changchun suburb. First of all, the foundation structure and load of the new green retaining wall are compared with that of the traditional retaining wall. Using the new calculation model, the dead load earth pressure is generated according to the fill weight without considering the surface uniform load. Coulomb active earth pressure is used to calculate and increase coefficient is introduced to make the distribution of earth pressure form a broken line. Secondly, taking the retaining wall of a construction project in Changchun as field experiment, the force of reinforced retaining wall is tested. The experimental results show that after the construction and completion of the green retaining wall, the stress range of the tension bar in the wall is smaller than that of the total fracture tensile force, and when the tension bar is subjected to external force, the variation of the earth pressure is similar to that of the parabolic type. It is proved that the new design model of retaining wall is feasible.
