摘要:
软土地基上水闸的沉降问题历来为水利学者们所关注的热点之一,重点关注复杂软土地基的参数变化对水闸整体沉降量的影响。以某实际水闸闸室结构为例,借助数值仿真分析手段,采用Mohr-Coulomb模型模拟复杂软土地基,计算水闸在不同地基参数情况下的沉降量,并基于正交试验法分析地基参数的敏感性,为沿海地区水闸枢纽结构安全设计提供可靠依据和技术支撑。结果表明,在较为复杂的软土地基上,土的弹模与密度是影响水闸沉降量的重要因素。
Abstract:
The settlement of sluice on soft soil foundation has always been one of the hot issues concerned by hydraulic scholars, especially focusing on the influence of parameter changes of complex soft soil foundation on the overall settlement of sluice. Taking an actual sluice chamber structure as an example, with the help of numerical simulation analysis methods, the Mohr-Coulomb model was used to simulate complex soft soil foundations, the settlement of the sluices under different foundation parameters was calculated, and the sensitivity of foundation parameters was analyzed based on the orthogonal test method, which could provide reliable basis and technical support for the structural safety design of sluice hubs in coastal areas. The results showed that the elastic modulus and density of the soil on the complex soft soil foundation were the important factors affecting the settlement of sluice.
