格栅状粉喷桩在深厚淤泥质软土层中桥墩防护的应用

Application of Grid Powder Spray Pile in Pier Protection in Deep Silty Soft Soil Layer

采用有限元软件对格栅状粉喷桩在深厚淤泥质软土层中桥墩防护进行了数值模拟计算,并通过工程完工后实测桥墩顶竖向、水平变形量与模拟计算分析结果进行对比,格栅状粉喷桩在深厚淤泥质软土层中桥墩防护的应用效果较好,可为类似项目提供参考依据。

This paper used the finite element software to conduct the numerical simulating calculation of the pier protection using the grid powder spray pile in the deep silty soft soil layer.After the construction,comparing the measured vertical and horizontal deformation values of the pier top to the simulated calculation result,it can be concluded that the grid powder spray pile had a good effect on the pier protection,providing a reference for similar projects.
