湿陷性黄土广泛分布于我国东北、西北、华中和华东部分地区,在湿陷性黄土地基上进行工程建设时,必须考虑因地基湿陷引起的附加沉降对工程可能造成的危害。本文针对湿陷性黄土地区给水排水管道工艺、结构特点,通过分析湿陷性黄土的特性,对该种地质条件下给水排水管道管材选用、管道基础、地基处理、管道接口等结构设计问题进行分析和探讨,并提出建议。
Collapsible loess is widely distributed in parts of northeast, northwest, central and eastern China. When project construction is carried out on collapsible loess foundations, it is necessary to consider the possible damage caused by additional settlement caused by foundation collapse. Based on the analysis of the characteristics of collapsible loess, this paper analyzes the structural design issues of water supply and drainage pipelines selection, pipeline foundation, foundation treatment, pipeline interface and so on under the geological conditions for the characteristics and structure characteristics of water supply and drainage pipelines in collapsible loess areas. And explore and make recommendations.
