高强预应力管桩在城市密集建筑地区软弱土层应用时。因周围土体受到扰动和破坏而产生较大的挤压应力,引起超静孔隙水压力,促使土颗粒向约束力小的方向位移。并使周围土体产生隆起,文章指出采取综合预防措施可使桩对周围环境的影响得到有效控制。
High-strength prestressed pipe piles are applied to the soft soil layer in dense urban construction areas. Due to the disturbance and damage of the surrounding soil, a large compressive stress is generated, causing the excess pore water pressure, and the displacement of the soil particles in the direction of small binding force. The surrounding soil was raised and the article pointed out that adopting comprehensive preventive measures can effectively control the impact of the pile on the surrounding environment.
