| 摘 要： | 地层沉降及不均匀沉降控制是储罐建造安全性保障的重要环节。本文重点分析了加设碎石环梁强夯地层的沉降变形特征,综合比较了碎石环梁与混凝土环梁加固储罐地基土的环向、径向沉降与不均匀沉降差异;指出地层差异能影响两类环梁基础的地基土加固效果;考察了碎石环梁弹性模量改变对储罐地基土沉降规律的影响;比较了截面为矩形的混凝土环梁与梯形碎石环梁对储罐地层的加固效果;并给出了碎石环梁加固储罐地基土的工程建议。研究成果可为类似工程建设提供借鉴参考。

| Abstract: | Ground settlement and uneven settlement control is an important part of the tank construction safety. This paper analyzes the settlement deformation characteristics of tanks foundation added gravel ring wall in detail. The settlement and uneven settlement differences are compared for storage tank foundations added with gravel ring wall or concrete ring wall along both ring and radial directions. The relationships between elastic modulus of gravel ring wall and foundation settlement rules are analyzed. The different reinforcement effects of rectangular concrete ring walls and trapezoidal gravel ring walls are compared. Engineering suggestions of gravel ring walls used to reinforce the tank foundation are given in the final. The research results can have a great significance to similar engineering projects. |
